Application of the mode matching model to V-T relaxation in liquid CCl₄

Abstract

The mode coupling approach has been used to calculate the energy transition probability between vibrational and translational modes of colliding molecules in liquid CCl₄. This calculation is used to interpret Brillouin scattering and molecular dynamics simulation results in terms of the angle of approach of colliding molecules. By this approach we rationalize the dependence of vibrational relaxation times upon the symmetry of the modes involved and upon the temperature.
