The atmospheric chemistry of the alkoxy radical CF{sub 3}O produced in the photooxidation of hydrofluorocarbon (HFC) 134a has been investigated using Fourier transform infrared spectroscopy. CF{sub 3}O radicals are shown to react with methane and CF{sub 3}CFH{sub 2} to give CF{sub 3}OH. CF{sub 3}OH decomposes to give COF{sub 2} and HF. The rate constant for the reaction CF{sub 3}O + CF{sub 3}CFH{sub 2} (HFC-134a) {r_arrow} CF{sub 3}OH + CF{sub 3}CFH was determined to be k{sup 19} = (1.1 {plus_minus} 0.7) x 10{sup -15} cm{sup 3} molecule{sup -1}s{sup -1} at 297 K. The implications of our results for the atmospheric chemistry of CF{sub 3}O radicals and HFC-134a are discussed. 26 refs., 4 figs., 2 tabs.
