| 1 | Introduction to the Spectroscopic Effective Hamiltonian Description The Born-Oppenheimer approximation and matrix elements of terms in the effective molecular Hamiltonian that violate the BO approximation. Vibration, rotation, spin-orbit, interelectronic interaction. Hund's coupling cases. | |
| 2 | Spectroscopic Pertubations, Predissociation, and Autoionization Description Introduction to dynamical processes. | |
| 3 | Semiclassical Methods for Calculating Vibrational Overlap Integrals Description All coupling processes are mediated by vibrational overlap integrals, which are computed numerically. Semiclassical calculation of overlaps reveals physical factors controlling computed values: the length of the stationary phase region is controlled by the slopes of the potential curves at the intersection and the velocity in the crossing region. | |
| 4 | Wavepackets and Landau-Zener Description What happens in the vicinity of a curve crossing? |
