A pulsed TEA CO2 lager was used for the IR photolysis of CCl3F. The dissociation fragments were detected by the methods of laser induced fluorescence and the IR analysis of the final products. The final products were CCl4, CCl2F2 and the three isomers of C2Cl2F2. The dissociation process of CCl3F and the possible reaction channels for the formation of the tinal products were discussed.
