f CDC13 (0.3 Torr) and with the addition of CHC13 and AI as bath gases. The laser absorption cross section was also measuredas a function of incident fluence in the range 0.01-0.7 J/cm2. The reaction probability per pulse was measured at fluencesof 7-60 J/cmZ as was the effect of added CHCl, and Ar at 20 and 33 J/cm2. The experimental results were modeled witha master equation with explicit consideration of rotational and anharmonic bottlenecks. The calculations in the high-pressureregion allowed obtainment of information about the energy transferred by collision of the vibrationally excited CDC1, withCHCl, and Ar. An energy-dependent value of (AE)d produces the best fit to the experimental results.
