A model based on :iemiclassical collision theory is presented to describe the dephasing of vibrationally excited molecules in a Iiquid. It is sholvn that fluctuations of the vibrational frequencies, which are uuzed by the intermolecular interaction, lead to phase rc:laxation of 3 coherently excited

Based upon the results reported here for phenyl acetylene and the results of other investigators' studies, a working model of phase relaxation in polar molecular liquids is proposed. The model rests upon the established concept of a phase annihilation operator' and a postulated phase conduction band
