Physical Chemistry II: Quantum Chemistry
物理化學二：量子化學 ( Lectured in Chinese)
30 units
This course aims to provide an introduction to the fundamental concepts in timeindependent quantum mechanics and approximation methods useful in physical chemistry, with an emphasis on the descriptions of manyelectron systems and spectroscopy. The lectures will be divided into three parts: 1/3 with focus on basics of timeindependent quantum mechanics and using quantum mechanics on simple systems, 1/3 with focus on electronic structures of atoms and molecules and the molecular orbital theory, and the last 1/3 with applications of quantum mechanics to spectroscopy.
