ON THE CALCULATION OF RESONANCE RAMAN-SPECTRA

A general formalism for resonance Raman scattering is presented which treats both linear and quadratic electron-photon interactions, The tim e correlation functions which are involved in resonance Raman scatteri ng both from a single vibronic state and from the initially distribute d vibronic states are calculated, The expressions are exact for a disp laced-distorted oscillator system at all temperatures, The effects of distortions of potential energy surfaces on absorption, resonance Rama n excitation profiles and resonance Raman spectra were also investigat ed quantitatively.
