Office Hours: 11-12 AM daily, by appointment, or anytime you can find me inside the office when the door is open.

DESCRIPTION: Chemistry 461 is the first semester in the Physical Chemistry sequence. We will study quantum mechanics, spectroscopy, and computational chemistry this semester. We will detail the following topics:

The failures of classical physics in describing the nature of the atom

Preliminary models prior to the advent of quantum mechanics

The wave equation and wave mechanics

The postulates of quantum mechanics

Basic quantum mechanical models: Particle-in-a-box, harmonic oscillator, and rigid rotor

The hydrogen atom

Multiple electron and multiple atom systems, and approximation methods

Computational chemistry

Atomic and molecular spectroscopy

In Chem 462, we will cover statistical mechanics, thermodynamics, and kinetics. Most of you will also be taking Chem 464 next semester as well, where we will explore various laboratory experiments involving physical chemistry topics.

PREREQUISITES: Math 113 or 215 and Chemistry 351. Math 316 or 341 and Physics 121 are recommended. Math 119 is allowed as a prerequisite for chemistry education majors, but please be advised that you may need to “catch up” in some deficient areas. Please see me as soon as possible if you took Math 119.

REQUIRED TEXT: McQuarrie & Simon, "Physical Chemistry: A Molecular Approach", University Science Books, ISBN 0-935702-99-7, 1997. We will cover most of Chapters 1-10 and 13 in the text.

STRONGLY RECOMMENDED: Cox, "Solutions to accompany Physical Chemistry: A Molecular Approach", University Science Books, ISBN 0-935702-43-1, 1997. You don’t have to get this book, but you really, really should. This book contains the solutions for all problems in the text, and is meant to assist you when you feel you’re completely stuck. WARNING: You must be careful not to use the solutions manual as a ‘crutch’. Work problems as completely as you can before referring to the solutions manual. Or, as James says, “Be ye doers of the word, and not hearers only, deceiving your own selves.” (James 1:22)

OTHER MATERIALS: You should have a scientific calculator. Only non-memory, non-graphical calculators will be allowed in the Testing Center; you can pick up an inexpensive one at the Bookstore if you don’t already have one.

We will do some projects using spreadsheet programs (Excel), MathCad, or some molecular modeling software. I assume you learned the basics of spreadsheet operations somewhere previously. We’ll cover other software as needed.

Lecture notes, assignment calendars, and schedules will be available online on my webpage (address given in class). Please check this often for additional information.

GRADING:

Your final grade will be based on a weighted average of the total possible points available in the following categories.

3 Midterm examinations (in the testing center) 60 %

Final Examination 20 %

Homework assignments 20 %

Your letter grade will be determined as follows:

A / 100.0%-90.0 %
A- / 89.9%-86.0%
B+ / 85.9%-82.0%
B / 81.9% - 75.0%
B- / 74.9%-72.0%
C+ / 71.9%-68.0%
C / 67.9%-64.0%
C- / 63.9%-60.0%
D+ / 59.9%-57.0%
D / 56.9%-54.0%
D- / 53.9%-50.0%
F / 49.9%-0.0%

Your score will be rounded to the nearest 0.1 percent. I reserve the right to adjust the grading scale, but any adjustments will be made down, not up (e.g., the cutoff for A will not be raised to 91, but might be lowered depending on various factors). Grades will be posted periodically outside my office. Please email me as soon as possible with either a 4 number code or a pseudonym you would like to use as your designation.

EXAMS: Midterm examinations will be write-on tests covering concepts discussed in class, including general descriptions, derivations, and application problems. They will be spaced about equally through the semester. The final examination will be similar in construction to the midterm exams, but will be comprehensive.

ASSIGNMENTS: Homework assignments will come from the textbook problems, and will be turned in every 1-2 weeks. Completing and understanding the homework assignments is essential to performing well on the exams and mastering a challenging subject such as this one.

Additionally, during the semester you will be expected to locate, study, and summarize three physical chemistry research papers from the scientific literature written in the past 5 years. Summaries will be due on September 23, 2005, October 21, 2005, and November 18, 2005.


Papers must be chosen from the following journals:

One from Journal of Physical Chemistry A (not B), available online at www.pubs.acs.org

One from Journal of Chemical Physics, available through interlibrary loan.

One from any other journal, where the article deals with some aspect of quantum mechanics or spectroscopy. When in doubt, please run the abstract by me.

Your summary should include a complete citation (author/s, journal name, volume, pages, year), a brief description of the paper’s main results in your own words, why you (not the authors) think the results are important, and why you (not the authors) think the work is interesting (if you think the work is not important/interesting, please explain this as well). Your summary should be no longer than one single spaced page. The purpose of this exercise is 1) to expose you to current fields of research in physical chemistry, 2) to become familiar with searching tools used to locate scientific articles, and 3) practice a scientific writing style comparable to what you encounter in the journals. I do not expect you to have a thorough grasp of the subject matter discussed in the paper(s); however, please come discuss it with me if you need help getting at least a basic idea of what is being talked about.

LATE ASSIGNMENTS:

Late work is not only annoying, but it cultures a bad habit that future internship providers, employers, graduate degree advisers, etc., loathe. The following policy will be in effect for late homework assignments (including weekly assignments and paper summaries):

1-3 days late 10 % deduction

4-7 days late 20 % deduction

7-14 days late 40 % deduction

ABSOLUTELY NO WORK will be accepted if it is more than 14 days late. Work is considered late if it is turned in after the beginning of class on the due date.

SEMINAR SERIES: You have the opportunity to gain up to 2 % extra credit by attending the Chemistry department seminar series lectures. These presentations are made by experts in all fields of chemistry at regional universities and other institutions. Credit is earned by attending the lecture and placing your name on a sign up sheet. In addition, several chemistry majors will be presenting seminars on their internship experiences over the summer. For these seminars, you will be expected to fill out an evaluation form to provide some peer-review feedback. Points are awarded according to the following formula

Where n = the number of seminars attended. So, the more seminars you attend, the more points you will receive for each successive seminar.

HELP SESSIONS:

Periodically, I will hold a help session at a time and place to be determined. You are not required to attend these sessions, and no new information you are directly responsible for will be discussed. But I will go over some information on those days that may help you understand other information. For instance, we may review concepts of differential equations that may help in understanding the wave equation, or we may just work some problems.

Honor Code

“The just man walketh in his integrity…” (Prov. 20:7) All aspects of the BYU-Idaho Honor Code will be observed in class. After taking an exam, do not discuss any aspect of the exam with other students until the exam has closed.

Preventing Sexual Harassment

Title IX of the Education Amendments of 1972 prohibits sex discrimination against any participant in an educational program or activity that receives federal funds, including Federal loans or grants. Title IX also covers student-to-student sexual harassment. If you encounter unlawful sexual harassment or gender-based discrimination, please contact the Personnel Office (496-1130).

Students with Disabilities

Brigham Young University-Idaho is committed to providing a working and learning atmosphere that reasonably accommodates qualified persons with disabilities. If you have any disability that may impair your ability to complete this course successfully, please contact the Services for Students with Disabilities Office (496-1158). Reasonable academic accommodations are reviewed for all students who have qualified, documented disabilities. Services are coordinated with the student and instructor by this office. If you need assistance or if you feel you have been unlawfully discriminated against on the basis of disability, you may seek resolution through established grievance policy and procedures through the Personnel Office (496-1130).

Retake Classes (From the University Catalog)

Retake classes replace the credit and grade of a previously completed equivalent course. The most recent completed course is calculated into the GPA and earned credits. Previous courses remain on the transcript and are designated as retake classes.

Students are allowed a maximum of four retakes during their BYU-Idaho study, regardless of whether it is a retake of a class with an awarded grade or a “withdrawal." Exceptions are considered on a case-by-case basis. Petitions are available at the Registrar’s Office. Retakes occur when retaking BYU-Idaho classes previously completed at this University, or retaking a class at BYU-Idaho previously completed at another institution which has been determined to be an equivalent course by the applicable academic department.

Retake of BYU-Idaho classes at another institution is not recognized as a retake unless approved by the Exceptions to University Policy Committee.

Students who transfer must recognize that a transfer institution may not accept the retake class per this definition.

About the instructor:

I started right here at BYU-I (Ricks), graduating in 1993 with an associates degree. I received my bachelor’s degree at Boise State University in Idaho, and my PhD in chemistry at the University of Utah. Prior to coming here, I worked at the National Institute of Standards and Technology in Gaithersburg, MD, and Battelle as a research scientist studying environmental applications of microwave spectroscopy.

My wife’s name is KyoungHwa (Ricks ’94), and we have four children, including two sets of twins.

PHILOSOPHY:

“Chemistry is the science of the behavior of aggregates of atoms and molecules and as such underlies all the material sciences. Studying it, we conclude that chemical laws follow from wave mechanics and the coulomb law of attraction between electrons and positively charged nuclei. Learning this and implementing it is science. The existence of such amazing unity and simplicity of design brings a sense of awe inspired only by an artistic masterpiece. With this comes once again an acute awareness of the Master Designer.” – Dr. Henry Eyring , “The Faith of a Scientist”
