Effective Dipole Moment Operator for C_(4v) Molecules. Case of Z -resonances

摘要

The effective dipole moment operators for the interacting fundamental nondegenerate v_n bands of different symmetry and degenerate v_t bands are presented. Using symmetry properties of the effective dipole moment parameters, the transition moments are expressed and well-known Herman-Wallis factors are constructed. The case of strong Z-resonances between fundamentals is considered.
