Atmospheric Chemistry of CF3O Radicals: Reaction with H2O

Article abstract of DOI:10.1021/j100131a033

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) x 10^-17 cm³ molecule^-1 s^-1.Implications for the atmospheric chemistry of CF3O radicals are discussed.
