Abstract: The infrared multiphoton dissociation (IR MPD) of CF_2HCl by measuring the C_2F_4 product after laser irradiation is investigated, The dissociation fraction of CF_2HCl as a function of the CF_2HCl pressure, laser energy fluence and number of laser pulses is measured. Under the low pressure condition the bottleneck effect is observed. Under the collision condition the dissociation fraction of CF_2HCl is affected by the competition between rotaional hole filling (collisional repoputation of pumped rotational states) and collisional deactivation of excited CF_2HCl moleculae.
