Abstract:
Influence of microscopic inhomogeneity in binary liquid mixtures on their vibrational spectra is studied by doing calculations on a model liquid system. The concentration dependence of the noncoincidence effect (NCE), which is a feature of vibrational bands related to the intermolecular resonant coupling of vibrational modes, is analyzed. It is suggested that observation of convex behavior of the NCEs for the vibrational bands of both species, especially that of the less polar species, in a binary liquid mixture is an indication of the occurrence of microscopic inhomogeneity.
