摘要: A new formulation of the theory vibrational relaxation, based on Zener's semiclassical approximation, is presented here. The relaxation rate shown to be proportional spectral density force exerted oscillator by its environment. isolated binary collision derived, but only with condition that frequency much smaller than frequency. This requirement not satisfied in a liquid; we conclude Litovitz's application liquids justified. possible relation between and self‐diffusion coefficient liquid discussed.
