An investigation of laser intensity and temperature effects in the time-resolved infrared multiphoton dissociation of chlorodifluoromethane

The abs. :CF2 concn. is measured in situ and in real time by UV-absorption spectroscopy in the IR multiphoton dissocn. of CF2HCl during and after the laser pulse. The :CF2 prodn. rate is measured as a function of the laser intensity and the temp. at 9.17 mm. This rate increases with the IR intensity and temp. for nearly the whole range of conditions applied. At the highest temps. attained the :CF2 prodn. rates start to decrease with increasing temp.
