Temperature Dependence of HE(v sub 1 = 1) + HF(v sub 2 = 0) Vibrational Relaxation.
Abstract
A kinetics model of infrared laser-induced fluorescence experiments has been used to simulate the experimental quenching rate coefficients reported between 300 and 4000 K for the vibrational relaxation of HF(v 1 = 1) by HF. This rotational nonequilibrium model is based on the predicted energy-transfer mechanisms in hydrogen fluoride systems reported in a trajectory study by Wilkins. This model includes v yields R, R yields v, R yields (R', T'), and (R', T') yields R energy-transfer processes. A key process is nonresonant vibrational-to-rotational intramolecular energy transfer in which HF(v 1 = 1, J 1) terminates on high J 1 states of v 1 = 0. No mechanisms involving dimerization appear to be necessary in understanding the inverse temperature dependence of the reported quenching rate coefficients.
