Resonant and Near‐Resonant Rayleigh and Raman Scattering for a Diatomic Molecule

Abstract

Using the results of a unified theory of scattering in the time‐independent (narrow exciting line) limit, excitation profiles for Rayleigh and Raman cross sections have been calculated for an actual diatomic molecule from over 8000 cm−1 off resonance into the resonance region. Three interference effects, a “vibrational level interference”, an “on‐resonance Franck—Cordon interference”, and “off‐resonance interference,” are discussed.
