Abstract

Resonance Raman scattering was extensively studied at the excitation frequencies close to molecular electronic absorption bands. Much less attention was given to phenomena that occur if excitation is done close to, or within, the IR absorption bands with the resolved rotational structure. We analyze the dispersion of the light­scattering tensor, <v’J’|α_ik|vJ>², (i,k = z,x), for different types of pure rotation and vibration-rotation transitions in nonsymmetric diatomic molecules in the spectral range of fundamental bands.
