in final rorm 16 Augusl 19R5 1 Introduction Though there had been earlier work on vibratronal relaxatron in hqurds [l] , Callaway and Ewmg's report of the vrbratronal relaxation rate for liquid N2 [3] produced a consrderable amount of interest and actrvity IJI the area of vlbratronal energy transfer and relaxatron in the hqurd phase. Much of the work has focused on neat dratomic hqurds or drlute solutrons of dratomrc gases III cryogenic liqurds Various Isolated binary colhsion (IBC) models have been extensively used to descrrbe energy transfer m such systems [3] -These models essentrally treat liquids as lugh densrty gases. Relaxation rates m hqurds are thus compared to gas phase results by correcting the gas phase rates, at the desued temperature, for the change in density and the liquid radral drstribution function The JBC models have been prunarily employed to describe vrbratron to translatron/rotatron (V + T/R) relaxation, where the melasticrty hw 1s much larger than kT_ When wr 5 1, where w is the frequency of the relaxmg mode and T the hfetime, only mfrequent, hrghly lmpulslve colhsrons, whrch occur at the repulsive part of the potential, contrrbute to the relaxatron rate The effects of three-body collisrons, interference between successive collisions and long range interac-' Presenl addrcs~ Asrospm
