英文摘要: The reaction of CH radical with O-2 has been experimentally investigated by time-resolved Fourier transform IR emission spectroscopy. CH radicals were generated by multi-photon UV laser photolysis of bromoform (CHBr3) in gaseous phase. Highly vibrationally excited product CO (nu=1-12) with a near Boltzmann distribution was observed after the reaction. The vibrational temperature of CO is estimated as high as 14400 1400 K and the averaged vibrational energy is about 25.8 kcal.mol(-1). The emission intensity of CO is not sensitive to the quenching gas, which indicates that there is no early barrier in the reaction of CH+O-2. However, the theoretically predicted product CO2 has not been found in the experiment.
