This course provides an introduction to the basic principles of quantum mechanics and their application to problems of chemical interest such as chemical bonding, chemical reactivity, and molecular spectroscopy. Emphasis is placed upon developing an understanding of the quantum mechanical basis for classical chemical concepts and introducing students to current research applications. The laboratory provides an opportunity to utilize quantum mechanics in the interpretation of optical and magnetic resonance spectroscopy measured on the modern instruments available in the department. Several seminar sessions give the student direct experience with computational techniques in modern quantum chemistry. Computer experience is desirable. Lectures: three hours a week; laboratory: four hours a week. Evaluation is based on problem sets, laboratory work, an hour test, and a final exam. Prerequisites: Chemistry 301, 302 or equivalent background in physics.
