    Student Learning Objectives:

    In this course, encompassing Chem 410A and Chem 410B, we will examine in detail the theoretical framework that justifies all chemical laws. The student successfully completing the course will be able to accomplish the following outcomes.

    Outcome Activity Assessment
    Analyze diverse chemical systems and reduce them to their principal chemical and physical components and interactions for the purposes of mathematical description. Students will be presented with derivations of fundamental principles through lecture and reading, with example applications discussed with the class as time permits. New applications of these principles will be presented as word problems for the students to solve on examinations.
    Predict the outcome of molecular processes (including diffusion, interaction with radiation, and chemical reaction) from a set of initial conditions. Lecture will demonstrate how principles of chemistry and physics aid in predicting the dynamics of molecular systems. Students will practice applying these concepts in online homework problems with unlimited attempts. New systems and initial conditions will be presented as problems for the students to solve on examinations.
    Calculate or estimate structural properties of individual molecules and small groups of molecules using principles of quantum mechanics. (Chem 410A) Lecture will demonstrate how quantum mechanics describes systems at the molecular scale. Students will practice applying these concepts in online homework problems with unlimited attempts. New applications of these principles will be presented as word problems for the students to solve on examinations.
    Use Excel and Maple to carry out several basic operations for the analysis and visualization of scientific data (Chem 410A lab). Students will work through several guided problems of growing complexity in data analysis, data presentation, and numerical simulations. Most activities will include a final component where data is given to the student to analyze as part of their score for the day's project. In addition, quizzes on selected topics will be presented throughout the semester following the guided portion of the relevant lab.
    Calculate or estimate dynamic properties of large sets of molecules using principles of statistical mechanics, chemical thermodynamics, and reaction kinetics. (Chem 410B) Lecture will demonstrate how classical physical chemistry describes systems at the laboratory scale. Students will practice applying these concepts in online homework problems with unlimited attempts. New applications of these principles will be presented as word problems for the students to solve on examinations.

    Meeting these objectives should allow the student to eventually build a meaningful intuition regarding chemical behavior based on a unified foundation of chemical theory.

    Physical chemistry is a fairly demanding course, and we spend little time reviewing material from the foundation courses that come earlier. Enforcing the prerequisites allows us to better match the course to those students who have at least partly established that foundation through their prior coursework. We do not enforce all the prerequisites at registration because this would make it impossible for many qualified transfer students to register. However, students who do not fulfill the course requirements listed as detailed below may be dropped from the course by the instructor:

    If you satisfy any of these requirements by coursework at a different institution, it may be necessary to show the transcripts for that work to the instructor.

    CHEM 410 is not a math class, and so I try to avoid unnecessarily lengthy mathematics in the problems. Usually. However, mathematics is our principal tool, and you need to be very comfortable with elementary algebra, geometry, and calculus (up to derivatives, simple integrals, and power series). The math is all manageable one step at a time, but there will sometimes be many steps.

    This is pretty much a physics class, however. In Chem 410A in particular we will call on results from mechanics and electromagnetism to justify some of our conclusions about atomic and molecular structure. You are probably familiar with the concepts if you've taken first-year physics, and we will introduce (but rarely prove) any equations from physics that we'll need before we use them.

    There is an introductory chapter ("Chapter A") to the text that summarizes the prerequisites we will rely on most often. Your texts for previous math and physics courses should help you if you're rusty in those areas.

    Course Material

    Condensed to one sentence, the course covers principles of atomic and molecular structure, molecular interactions, statistical mechanics, chemical thermodynamics, and chemical kinetics.


    The Chem 410A/B sequence covers the fundamental physics of chemical systems, including structure, energetics, and interactions of molecules. The material can be applied to inorganic, organic, and biochemical molecules and reactions. In fact, most of the important results in physical chemistry will already be familiar to you from general chemistry. If you find the details of our work in this class obscure the results, you may want to go back and look at the relevant section of a general chemistry text.

    The primary reference for the course is still the lectures themselves. No material is covered on the tests that has not been discussed in class, and occasional lecture topics may appear on the tests even if they are not included in the reading. But if you read ahead, you may find the lectures more useful, and your note-taking may be reduced to adding comments to the text rather than transcribing the entire lecture.


    Physical chemistry examines chemical phenomena both on the scale of individual atoms and molecules (the microscopic limit) and on the scale of thousand-gallon chemical reactors (the bulk or macroscopic limit) and bigger, as well as everywhere in between. In this class, we build from the microscopic limit to the macroscopic:

    1. quantum mechanics of atoms
    2. quantum mechanics of molecules
    3. molecular interactions at microscopic scale
    4. statistical mechanics and extrapolation to the macroscopic limit
    5. thermodynamics and bulk properties of non-reactive systems
    6. bulk reaction thermodynamics and kinetics.

    This differs from the organization of most textbooks in the field, which start with classical thermodynamics and kinetics, and then introduce quantum mechanics and statistical mechanics in the second half. I hate that, so instead we're using my own textbook as your reference. But no single teaching style or book works for everyone, so other textbooks are available at Love Library (see below).

    A more detailed breakdown of the course follows the chapters of the 2-volume textbook in sequence:

    Grading Scheme

    Overall Grading Scheme

    Final grades will be assigned on the following scale:

    A ≥85%
    B ≥70%; <85%
    C ≥55%; <70%
    For CHEM 410A, the totals from the lecture and the lab parts of the course are combined in a 75:25 ratio before determining the final grade.

    Lecture Grading Scheme

    Note that for CHEM 410A the following table applies only to the lecture part of the course:

    # assignment points each points total % lecture grade
    6 homework sets 20 pts (drop lowest score) 100 10%
    ≈50 CourseKey questions 1–2 pts 50 5%
    4 drills 25 pts 100 10%
    6 20-minute exams 100 pts (drop lowest score) 500 50%
    1 cumulative final 250 pts 250 25%

    Lab Grading Scheme (410A only)

    The lab grade is based on several 10-point labs, and a few 10-point quizzes. The lab and lecture instructors (not always the same person) will determine the grading scale for the labs, and at the end of the semester the total lab scores will be normalized to the lecture grading scale below (so that for example a high B in lab is converted to a high B on the lecture grading scale). The final score will then be computed as
    0.25 × (normalized lab score) + 0.75 × (lecture score).

    Go to top



    These are 10-minute quizzes on the most basic material, mostly review material from prerequisite classes such as General Chemistry. These are sometimes directly relevant to the lecture material, and the dates on which they are given may be changed during the semester to accommodate the variable lecture schedule. Because it should not be necessary to spend a lot of time preparing for these, I will allow myself to give a drill on only three day's notice. Drill material will usually not be reviewed in lecture.

    Problem Sets (Online Homework)

    One problem set of online Mastering Chemistry homework problems will be given before each exam. I will make available a number of problems, worth 1 or 2 points each, with a maximum score of 20 points per problem set. You are encouraged to try as many problems as you can manage, but you only need to complete 20 points' worth of problems to get full credit. These will normally be due the Monday before each exam, and the initial problems will be posted about two weeks before that. I may continue to add problems to the set up until it is due, but you will have at least one full week to work to complete your 20 points. No credit will be given for late problem sets, so please get your 20 points done before the due date.

    Most of these will be based on the more straightforward lecture material. The primary goal of the homework is to encourage the class to prepare for the exam more than two days in advance. The homework problems are not intended to exactly represent problems that will appear on the exams. Studying solutions to these assignments alone will be of only partial benefit in preparing for the exams.

    The homework also provides an opportunity to illustrate some applications drawn from material covered in lecture, and these may contain tougher mathematics than will be necessary on the exams. If you're spending more than 15 minutes on one problem and not making progress, please come to the office hours or email me or use the Blackboard discussion forum.


    CourseKey is an interactive clicker-style classroom engagement system that uses an app on your mobile device. I hope to have one or two CourseKey questions per class, generally worth 1 point for participation and 1 point for the right answer. Like the homework, there will be a maximum number of possible points (50 for Coursekey) but multiple chances to get those points. If you miss a class, or have an isolated case of technical trouble, we won't worry about it because you will can make up the points another time. Although I will not be using CourseKey to take attendance, you should still come to class fairly often to be sure of getting all 50 points.

    To use CourseKey:

    There is a video on getting started with Coursekey available. Should you require assistance or technical support, please contact CourseKey Support Team directly by email, visiting the Help Center, or by using any of the tools found in the app itself under the “Support” button. Please note there is a live chat Monday through Friday, 9:00 am to 5:00 pm PST where you can talk immediately to our support team. Please remember that the Support Team will likely require specific user information to troubleshoot any issue you have may have.

    Exams and Final

    There will be six 20-minute exams and one 2-hour final. CHEM 410B has an additional, optional ACS final exam. For all exams and the final:

    Although the exams are all open-book, you must come to them prepared. You will have time only for very brief consultation of your notes. Attached to each 20-minute exam are what I deem all necessary tables, constants, and complicated equations. The final exam will offer you almost twice as much time per question, so will feel less rushed. But I find that the added time does not tend to greatly raise students' scores.

    The 20-minute exam on which you get your lowest score will be dropped from calculation of the final grade. If you are unable to take an exam for any reason, that exam will become your dropped score. There are no make-up exams. Please beware of purposely dropping any exam to make room in your schedule for something else. Throughout the two-semester sequence, what we cover on one exam is always based on material that the previous exams covered, so it doesn't pay to purposely neglect any section of the course.

    The final exam will review all of the course material for the semester, and provides an opportunity to improve recorded scores on some problems from the short exams. Your exam scores are recorded question-by-question. After writing the final, I will match some of those questions to questions on the 20-minute exams which covered the same topic. If you score higher on one such question on the final than you did on the corresponding question on the 20-minute test, I will raise your grade on the 20-minute test. But don't count on a lot of help from this: because there are not nearly as many questions on the final as on the set of 20-minute tests, the final will not be able to correct substantially for routinely poor performance on the 20-minute tests. Also, the final is not capable of changing grades as much as one might think. The wide grade ranges of the grading scheme (with a 20% range for a B, for example) make it hard for any one assignment to shift the final total by a whole letter grade.

    ACS final exam in CHEM 410B

    Two final exams will be offered in CHEM 410B only:

    Your best score of the two finals will be your score on the final for CHEM 410B. Therefore, it cannot hurt your grade to take the ACS exam. A review of CHEM 410A material will be offered. Scores from the earlier, official final exam will be made available only after the ACS exam. (It's unlikely that the regular exam will be graded before the ACS exam anyway.)

    Labs (410A only)

    The lab manual will allow you to prepare for each lab. While you may consult with each other before the lab, full credit will not be given for lab assignments that appear to be largely copies of the same file. Any part of the assignment may be modified upon your arrival in lab in order to encourage everyone to be ready to do their own work. The labs must be completed during the class period, in the assigned classroom; exceptions require prior consent of the instructor. If more than one lab section is being offered, then changing sections for a particular lab to accommodate a personal schedule conflict is allowable, provided that consent is obtained from the instructor(s) for both sections and that there are enough computers available.

    11. Introduction to quantum chemical molecular modeling (Gaussian 16).
    12. More quantum chemistry computations (Gaussian 16 and Solver).

    Missed Assignments

    This course cannot always be your top priority, and in consideration of this, the lowest score from each of (a) the problem sets, (b) the 20-minute exams, and (c) the regular CHEM 410A labs (not lab practical or lab quizzes) are all dropped. If you do not turn in one of these assignments for any reason, that becomes the dropped assignment. This is intended to accommodate emergencies such as illness, as well as professional obligations such as out-of-town conferences. In the event that other obligations or emergencies compel you to miss multiple assignments and you are concerned about your grade, then you may meet with me during office hours to discuss the possibility of taking an incomplete.

    SASC Accommodation

    Students who may qualify for special accommodations for these assignments should first seek authorization by contacting Student Disability Services at 619-594-6473 (Calpulli Center, Suite 3101). Students with that authorization should then contact me as early as possible so that we can agree on a suitable protocol for drills, quizzes, labs, and exams. We cannot retroactively apply special consideration for assignment scores. You are welcome to email me if you would like to set up an appointment outside regular office hours for that discussion.

    Additional Hours: Examples Session and 410A Calculus Boot Camp

    We have a lot of material to cover, and we will cover almost all of it. Lectures are therefore rather fast-paced, and it is often not possible to work through example problems during class time. To make up for this, please take advantage of my office hours to go over lecture material, sample problems, and to review quizzes and exams.

    Examples Session. In addition to the regular office hours, a totally optional examples session is held each Monday evening (starting the second or third week of class) from 5-6pm. This allows us to go over additional problems, and at a more leisurely pace. New material for tests is never introduced at these sessions, and attendance is not expected or required. If you choose to come, you may arrive and leave anytime during the session, but please bring questions about the material or suggestions for problems to work through.

    Calculus Boot Camp (Chem 410A only). A 3-day, 7am-8am review of basic calculus, focusing on the rote methods rather than the mathematical theory. This is completely optional. Nothing is graded, and no sign-up or regular attendance is required. The idea is to provide a chance for students who are concerned about their calculus skills to exercise them before it really matters. I do not try to make this interesting; it's just math drills, available for those who feel they might need it and are willing to make some extra effort.

    Studying Physical Chemistry

    You've reached a level of coursework where there's no reliable formula for success. I will be trying to grade each student based on their understanding of fundamental concepts that underlie all of chemistry, and their ability to apply those concepts to different situations. This is a lot to ask. I appreciate that your time is limited, and you want your study time to be wisely used, but it will be up to you to find what works best. It is possible to study many hours and still be disappointed by performance on the exam, so you need be honest with yourself about how to make your studying most effective. For example, reading the homework problems and then reading the solutions can feel very rewarding, but often does not prepare a student for the demands of putting together the solution on their own. Detailed solutions to many problems in the book are provided in the solutions manual, but I always try to write new problems and new kinds of problems for the exams.

    To pass the course it is usually enough to make sure that you can do the basic calculations. But to get an A, you will need to demonstrate that you can apply the principles we cover to new situations of my choosing. That requires testing yourself not just on how to use particular equations, but on why those equations work for particular situations, and what would happen if the situations were different. My hope is that an A will reflect a deep grasp of the most fundamental ideas in chemistry. I hope you'll agree that this is a goal worth considerable effort.

    My recommendations:

    1. Work lots of problems, but don't spend a lot of time on any particular one. The most difficult part of a good exam problem is right at the beginning: seeing what concepts we've covered that relate to the question. For that purpose, I think it's more valuable to see lots of different examples than to go into depth on a few.
    2. Don't assume that understanding a solution is the same as being able to solve a problem. It is much easier to make sense out of a solution that is presented to you than to come up with another similar solution on your own. Concentrate on how how you would start solving the problem that particular way. What in the problem makes it clear which equations are useful?
    3. Don't memorize a particular approach. Learning recipes for solving particular kinds of problems (a strategy that works well in General Chemistry) is only a small part of succeeding in Physical Chemistry. Some of these problems can be solved by rote, but not the really interesting ones, and I try to make the exam questions interesting.
    4. Try to ask yourself qualitative questions about the material. This is difficult, but once you get to the point that you can solve the purely numerical problems, you should be able to ask yourself what that answer means. Would the final value be larger or smaller if you changed the system somehow (more massive particle, bigger container, ...)? What if we asked the same question, but about a different system? These are the kinds of questions I ask myself when coming up with the problems.
    5. Make the lectures worthwhile by reading ahead if you can, and asking questions in lecture when you need to.
    6. Study with others and ask each other questions about the material. Test each other. The end-of-chapter problems begin with a set of "discussion questions." These would be terrible exam questions because they look mostly for qualitative, essay-like solutions (difficult to grade), but they are suggestions for the sort of questions you should be asking each other.
    7. Come to office hours and/or the Monday afternoon examples session, at least once, early in the semester. Find out if either of these is helpful before you look for alternatives.
    8. Keep thinking about the material. The material should make sense, if you can give yourself the time to think it through. That's the most rewarding thing about the class -- it shows how chemistry all fits together into one cohesive picture.

    Ultimately, the only way to guarantee success in the course should be to understand the material really, really well. Try to honestly assess your own understanding of the material, for example by seeing how reliably you can productively start to solve problems at the end of each chapter, and use that as your guide to what study techniques work best for you.

    Conduct of Class

    Please ask questions. If we really are in too much of a hurry, or if I just can't come up with a better explanation than I've already given, we may need to postpone the discussion until office hours. However, if the class is exceptionally quiet, it only encourages me to keep on talking and talking and talking.

    Please always disable any noisy electronic devices you have, such as cell phones and watch alarms, before you come into class so that they will not disturb us during lecture or lab. If you must use your phone during lab, please leave the room first. If you must use your phone during lecture, please stay away.

    The goal of the labs is for you to understand how to use the software to accomplish a specific task, and the assignment is there to keep your efforts focused. Please get assistance if you need it. In addition to asking the instructor questions, you are welcome to confer with each other during the regular labs, but only you and your instructor are permitted to edit your assignment. For example, other students should not type an expression into your Excel spreadsheet, or use your mouse to demonstrate how to change the appearance of your chart. This also means that you are never permitted to share a template spreadsheet with anyone else. This would be plagiarism, and the penalties can be harsh. Please also remember that the lab quizzes test the skills introduced by the regular labs, and for the quizzes no assistance from classmates is permitted, so you will want to know how to do your own work for these assignments.

    I prefer not to invest class time in discussing the course administration. Of course you may ask me to justify any aspect of the syllabus, but please reserve those questions for office hours or email, outside of our limited lecture time. Lab tends to quiet down towards the end of the lab period, and so I am also often available then for questions then about the lecture material or administrative issues.
