6.2 Polyatomic molecules 142 I Models of potential energy surfaces: (1) Empirical or semiempirical models (e.g., LEPS), (2) Single points ( ) by ab initio calculations using quantum chemistry. Problem: Fitting the surface to the computed points. I Kinetics and Dynamics: (1) TST = Transition State Theory (statistical theory), (2) Classical trajectory calculations (by solving Newton’s equations), (3) Fully quantum mechanical wave packet calculations (by solving the timedependent Schrödinger equation).
