Abstract

This paper reports the results of an extensive study of the internal energy-transfer processes that occur in benzene-argon collisions. We used laser-induced fluorescence (LIF) and information theory for determining the energy-transfer rates between internal states of benzene in the ground electronic state (1Aig). The use of information theory gives estimates for all of the vibrational energy transfer rates. These fit the experimental data reasonably well. However, some of the data do deviate from the information theory model. This suggests that the statistical assumptions of the model are not sufficiently restrictive. One such restriction may be in the number of vibration quantum numbers that change in a collisional event. The rates of vibrational energy transfer depend strongly on the vibrational energy defect.
