Kinetics of nonresonant vibrational energy exchange in binary mixtures of molecular gases

The variation of the temperature of a gas during vibrational relaxation is a unique source of information on the kinetics of vibrational-vibrational (VV) and vibrational-translational (VT) energy exchange, and the characteristic parameters of the temperature curve are related to the characteristic times of the VV and VT processes. The effect of kinetic cooling, in which VV exchange leads to a temperature drop, has been studied quite extensively 1]. It was shown in 2] that the characteristic parameters of the cooling curve are uniquely related to the VV and VT relaxation times.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 10, pp. 15–18, October, 1988.
