Average Collisional Vibrational Energy Transfer Quantities. The Exponential Model.
Abstract
The important collisional energy transfer ratio, gamma = <delta E>sub all/<delta E> sub d was examined by using a fitted classical approximation for the density of internal energy eigenstates. The exponential form of the collisional energy transfer probability function was applied to four model unimolecular reaction systems. Two parameters, the inversion temperature TI and the effective temperature Te (defined previously in I), were employed to develop a form for the parametric dependence of gamma on <delta E> sub d, energy level E and temperature T; these quantities are related to a reduced average energy transfer quantity E' sub e. Comparison was made with previous literature expressions for the inter-relationship between <delta E>sub all and <delta E>sub d for both exponential and stepladder models of the collisional transition probabilities.
