Abstract

Mutual effect of interparticle attraction and repulsion on isotropic Raman line contours and time correlation functions was studied. The theory of Burshtein et al. [Chem. Phys. Lett. 83, 335 (1981); 100, 155 (1983); Spectrochim. Acta 43A, 483 (1987)] was used, and broadening caused by repulsion forces was defined more precisely. The discussion of the results obtained was made with special reference to ionic systems (molten salts and salt glasses).

Abstract

Repulsional contributions into spectral shifts have been expressed in terms of derivatives of atom displacements with respect to vibrational normal coordinates. Attraction and repulsion have been shown to give a comparable contribution to the overall shift. Working ability of the formulae obtained for spectral shift calculations for molecular (HCl solution in CCl 4 ) and ionic (molten lithium and rubidium nitrates) liquids is demonstrated.
