Calculation of the vibration-rotation line intensities in the Raman spectra of gases

The method of irreducible tensorial sets is used for deriving general formulae describing the intensities of vibration‐rotation Raman lines of molecules of different symmetries. Using this method, generalization of the parameters characterizing isotropic, antisymmetric scattering, taking into account vibration‐rotation interactions, has been carried out. The effect of vibration‐rotation interactions on the Raman scattering cross‐section is considered.
