| Abstract: | The
mechanism of O(1D) reaction with CF3Br induced by photolysis of CF3BrO3 system at 253.7 nm
was studied. The final reaction products are CF2O, F2 and 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. |
