| Abstract: | Laser-flash photolysis of RBr/O3/SF6/He mixtures at 248 nm has been coupled with BrO detection by time-resolved UV absorption spectroscopy to measure BrO product yields from O(1D) reactions with HBr, CF3Br, CH3Br, CF2ClBr, and CF2HBr at 298±3 K. The measured yields are: HBr, 0.20±0.04; CF3Br, 0.49±0.07; CH3Br, 0.44±0.05; CF2ClBr, 0.31±0.06; and CF2HBr, 0.39±0.07 (uncertainties are 2σ and include estimates of both random and systematic errors). The results are discussed in light of other available information or O(1D)+RBr reactions. © 1998 John Wiley & Sons, Inc. Int J Chem Kinet 30: 555–563, 1998 |
