抄録

We report herein depolarized low-frequency Raman scattering measurements of liquid CCl4, CHCl3 and acetone. The reduced Raman spectra were analyzed for the first time using a relaxation function based on the multiple random telegraph (MRT) model of dielectric relaxation which takes into account inertia and memory effects. The imaginary part of the dielectric function of the MRT model reproduces the spectral profile of the low-frequency region of the reduced Raman spectra quite well. This indicates that the origin of the complicated central component of Raman spectra of liquids can be explained by intermolecular dynamics based on the MRT model.
