The effect of the energy density, laser radiation frequency, and resonance and buffer gas pressure on the process of multiphoton dissociation of CF/sub 2/HCl molecules was experimentally studied. The dependence of the threshold value of the energy density on the resonance gas pressure in long-wave tuning of the radiation frequency on the maxima of the spectra of linear and multiphoton absorption of /sup 13/CF/sub 2/HCl molecules was studied. A model which qualitatively explains the threshold character of dissociation and the increase in selectivity with an increase in the gas pressure and radiation pulse duration was proposed.
