摘要： 研究了CF3Br-O3体系在253.7nm紫外光照射下所引发的O(1D)与CF3Br的反应.O(1D)与CF3Br反应的最终产物为CF2O、F2和Br2,反应速率常数k为1.32×10-10cm3·mol-1·s-1.讨论了O(3P)与CF3Br反应的可能性、O(1D)与CF3Br反应的机理及外加气体对反应的影响等.

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.
