Chemistry 131A: Quantum Principles
Chemistry 131A: Quantum Principles (Winter 2014, UC Irvine) . Instructor: Professor A. J. Shaka. This course provides an introduction to quantum mechanics and principles of quantum chemistry with applications to nuclear motions and the electronic structure of the hydrogen atom.
It also examines the Schrodinger equation and study how it describes the behavior of very light particles, the quantum description of rotating and vibrating molecules is compared to the classical description, and the quantum description of the electronic structure of atoms is studied.
