Introduction to the Spectroscopic Effective Hamiltonian 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. |
Lecture 2![]() Play Video |
Spectroscopic Pertubations, Predissociation, and Autoionization Introduction to dynamical processes. |

Semiclassical Methods for Calculating Vibrational Overlap Integrals 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. |
