Vibration-Vibration Pumping in Hydrogen: Estimate of Induced Dissociation at 300 Degrees Kelvin,
Abstract
By means of the stimulated Raman effect one may produce in H2, D2 and in several other gases, a substantial population in the v=1 state. Subsequent to the pulse excitation v-v energy transfers rapidly generate a vibrational distribution which is approximately equivalent to 3000-4000K. Then, in H2 + D2 mixtures metathetic reactions occur. Here the authors report on a computer simulation of an experiment designed to estimate whether a measurable fraction of the hydrogen molecules reach the upper vibrational level and dissociate. Solutions of the coupled differential equations show that the anticipated hydrogen atom concentrations are too low to account for the observed H/D exchanges. These calculations also show that the conventional phenomenological rate equation for dissociation does not apply to this highly non-thermal distribution. (Author Modified Abstract)
