The influence of the population distribution function on the collisional relaxation of highly vibrationally excited polyatomic molecules is analyzed in a non-reactive system. Unimodal and bimodal energy distributions are considered. Calculations made with unimodal energy distributions showed that th

โฆ Synopsis
Energy removed from highly vlbratlonally excited polyatomic molecutes by polyatomic co&ion partners decreases with increasmg number of atoms in the hot molecule. The trend is qualitatively predicted by two quasi-statistical modek of energy transfer, and calculations of energy removal by the transittonal modes model mves agreement with experiment

The average downward collisional energy transfer () is obtained for highly vibrationally excited tert-butyl chloride, both undeuterated and per-deuterated, with Kr, N,, C02, and C2H4 bath gases, at ca. 760 K. Data are obtained using the technique of pressure-dependent very low-pressure pyrolysis. Re
