The dissociation yield and branching ratio in CO 2 laser-induced infrared multiphoton dissociation (IRMPD) of CF 3 CHClF were investigated by irradiation at 9R(20) 1078.6 cm −1 under an unfocused irradiation geometry (0.75-2.3 J/cm 2 ) and a mildly focused one (1.2-18 J/cm 2 ). By using a Br 2 -scavenging technique, it was revealed that the primary dissociation of CF 3 CHClF proceeded mainly via three-centered HCl molecular elimination and C-Cl bond rupture, with minor contributions of C-C bond rupture and HF molecular elimination at higher fluences. The secondary photolysis of the primarily produced species during the laser pulse to yield CF 2 and CClF carbenes depended strongly upon the laser fluence.
