The reaction of methylene radical CH2(X3B1)with molecular oxygen was investigated with Time-Resolved Fourier Transform Infrared spectrometer(TR-FTIRS). Pure CH2(X3B1)radicals were produced by UV photolysis of ketene at 351nm. Vibrationally excited products OH(or H2O) and H2CO were observed in the infrared emission spectra. The H2CO channel was verified as a product of elementary reaction. The nascent vibrational distribution of CO and CO2 were obtained. The most populated vibrational level was v=4 for both the CO and CO2.
