✦ Synopsis

The infrared fluorescence risetimes of the vs C-Cl stretching mode of CHsCl have been measured in CHsCl-raregas mixtures subsequent to laser pumping of the ve methyl deformation vibration with a Q-switched CO2 laser. The rate of rise of this fluorescence was found to be 80 f 8 msec-'/torr in pure CHsCl as reported earlier. The effect of rare gases on this process was found to be in reasonable agreement with SSH type theoretical calculations as well as similar trends in other V-V processes.
