Evidence is presented that CF3O radicals react with H2O in the gas phase at 296 K to give CF3OH and OH radicals. This reaction is calculated to be exothermic by 1.7 kcal mol-1 implying a surprisingly strong CF3O-H bond energy of 120 ± 3 kcal mol-1. Results from a relative rate experimental study suggest that the rate constant for the reaction of CF3O radicals with H2O lies in the range (0.2-40) × 10-17 cm3 molecule-1 s-1. Implications for the atmospheric chemistry of CF3O radicals are discussed.
