Resonance Raman scattering by a predissociative state: A study of nonadiabatic effects

Abstract

A coupled equation approach is used to study the excitation profiles of the resonant Raman scattering of a predissociative electronic state in a diatomic molecule. The method allows one to calculate also the photopredissociation cross section so that a comparison between the two processes can be made. Calculations are presented for a realistic system, the scattering from the predissociated B 3Π0+ state of IBr.
