Abstract
The vibrational energy distributions of HF and CO formed in the O(3P) + CF3C2H reaction have been measured by means of HF laser emission and CO laser resonance absorption methods. CO was found to be vibrationally excited to υ = 3 with a Boltzmann vibrational temperature of 2200 K. The observed CO distribution is consistent with those predicted by different statistical models, indicating the presence of a long-lived reaction intermediate (CF3CH=CO). The observed HF distribution (N1/N0 = 0.38 ± 0.06), however, was found to be twice as much as that predicted by these models, presumably due to the presence of other more exothermic secondary reactions, such as CF3CH + O and NO2, the photochemical source of the O atom.
