Physical Chemistry II
Chemistry 344

W.F. Polik

Course Objectives:  Chemistry 344 is a study of the quantum mechanical principles that are fundamental to understanding the properties of molecules.  We begin by recognizing the failure of classical mechanics to account for microscopic phenomena, and then develop a quantum mechanical approach to account for bonding and spectroscopy of molecules.  We will study several illustrative model quantum mechanical systems and then turn to the study of atoms and molecules.  In the process, we undertake a detailed investigation of molecular spectroscopy.  Through this course you will:

·        Recognize the limitations of classical mechanics in treating atomic and molecular phenomena.

·        Understand the concept of quantized energy levels and appreciate the role of Planck's constant, h, in quantum mechanics.

·        Use the formal postulates and techniques of quantum mechanics to solve the Schrödinger Equation and interpret its solutions.

·        Understand the properties of simple quantum mechanical models (particle in a box, harmonic oscillator, rigid rotator) and relate these results to molecular systems.

·        Learn to use perturbation theory and the variational method to solve complicated quantum mechanical problems, such as the electronic energy levels of atoms.

·        Understand the approximate separation of electronic, vibrational, and rotational energy levels in molecules.

·        Understand the molecular orbital theory of molecular bonding.

·        Interpret molecular spectra from a quantum mechanical viewpoint.

·        Develop skills in using mathematics, solving problems, and making oral presentations.

Text and Resources:  The following text and resources are required:

           McQuarrie, Quantum Chemistry, First Edition

           Polik, Lecture Handouts, Spring 2006

            There are also numerous texts in Van Wylen Library that you are encouraged to look through for additional insight under the call numbers:

           QC174 - QC174.12       Quantum Mechanics

           QD453 - QD469                        Quantum Chemistry

Homework:  Solving homework problems is an essential component of this course.  Homework problems are chosen to illustrate course content and to practice problem solving skills.  Working with other students to understand and solve homework problems is encouraged; however, the work you turn in must be your own.  Homework assignments are to be turned in at the start of the Friday lecture each week, except exam weeks.  Late homework will not be accepted.

            In order to assist you with the homework, the scheduled Wednesday afternoon discussion, 3:00 pm to 3:50 pm, will be devoted to student presentations of the problems due the following Friday.  All students are expected to attend the discussion sections.  Students will be assigned a homework problem to workout beforehand, make an oral presentation of the solution using the whiteboard, and answer audience questions about their solution.  Presenters will also monitor Chemboard and reply to questions related to their problem.

Exams:  There will be four exams, three of which will be given in class during the semester and the fourth during final exam week.  Exam problems will be derived from both the assigned homework and the lecture material and are designed to test your ability to put the concepts learned in the course to use.  The final exam will include both recently covered material and a standardized cumulative test.  The exam schedule follows:

Honor Code:  Academic integrity is assumed.  Do not cross the line between working with other students to solve homework problems and copying the solutions of others.  Verbatim copying of solutions presented in discussion section is specifically forbidden; however, you may use the presented solution as a guide as you work out each step of the solution on your own.  Violations will be dealt with according to Hope College's Code for Academic Integrity as stated in the Hope College Catalog.

Grading:  Your performance in the course will be evaluated as follows:

3 Homework Problem Presentations (@ 15 pts)

  45 pts

     7%

10 of 11 Homework Sets (@ 20 pts)

200 pts

   31%

4 Exams (@ 100 pts)
