Vibrational Relaxation of DF (v = 1-4) in D2, H2, N2, HF, and CO2

Abstract

The deactivation of the upper vibrational levels of DF by H2, D2, N2, HF, and CO2 has been studied with the technique of laser-induced fluorescence. The upper vibrational levels were produced by sequential photon absorption in which DF(v = 0) was pumped first to DF(v = 1) and subsequently to DF(v = 2), DF(v = 3), and DF(v = 4) by photons from a pulsed multiline DF chemical laser. The deactivation rates (V - V + V - R, T) for all the collision partners except D2 scaled with vibrational levels as v to the nth power with n = 1.9 to 2.0 for v = 1 to 4. Similar studies have indicated the somewhat larger value of n = 2.7 + or - 0.2 for HF(v) deactivation by diatomic molecules.
