Abstract
The spectral moments of ir and Raman bands of diatomic molecules in inert solutions are calculated by the help of recent stochastic theories of ir- and Raman-band profiles. Both vibrational and rotational motions are considered. It is found that for ir and rotational Raman bands, the stochastic theories produce expressions for the band moments which closely parallel the corresponding thermodynamic expressions. New expressions are proposed for the moments of isotropic and of vibrational-rotational anisotropic Raman bands.
