Abstract

Evidence is presented that CF3O radicals react with HzO in the gas phase at 296 K to give CFsOH and OH radicals. This reaction is calculated to be exothermic by 1.7 kcal mol- 'implying a surprisingly strong CF@-H bond energy of 120 f 3 kcal mol-'. Results from a relative rate experimental study suggest that the rate constant for the reaction of CF3O radicals with HzO lies in the range (0.2-40) X 10-17 cm3 molecule-1 sl. Implications for the ...
