Abstract
The emission spectra of vibrationally excited hydroxyl radical products formed in the ractions of alkyl radicals with O(3P) atoms are detected using a laser potolysis/time-resolved Fourier transform infrared spectroscopy technique. For the reactiokKetone, respectively. The observed initial OH(V) product vibratonal state distbution for the C2H5+O(3P) reaction is 0.18+or-}0.03, 0.23+or-}0.04, 0.29+or-}0.05, 0.23+or-}0.07 and 0.07+or-}0.04 for v=1 to 5. The population inversion is best explained by a direct abstraction mechanism for this radical-radical reaction. Vibrationally excited hydroxyl radicals are also observed in the O+ethyl, O+ethyl, O+n-propyl, and O+i-propyl reactions when using alkyl iodides as precursors of the alkyl radicals, although quantitative detail is not obtained.Citation
