Abstract: The mechanism of O(1D) reaction with CF3Br induced by photolysis of CF3BrO3systeMAt 253.7 nm was studied. The final reaction products are CF2O, F2and Br2. The rate coefficient of O(1D) reaction with CF3Br is obtained(k=1.3210-10 cm3molecule-1s-1). The possibility of O(3P) reaction with CF3Br and the influence of the added gases was also studied.

Key words: Tribromofluoromethane, Oxygen atom(1D excited state), Ozone, Uvlight
