Abstract:

The reaction of vinyl radicals with oxygen was investigated by Time-Resolved Fourier Transform infrared emission spectroscopy. The radicals were produced by the pulsed laser photolysis of C_2H_3Br at 248 nm. Vibrationally excited products of H_2CO(v1), HCO(v3), CO_2(v3, v), CH_3(v3), C_2H_2(v3), HO_2(v1), C_2H_2O_2(v3+v11), CO(v) formed in the C2H3+O_2 reaction have been observed. Four elementary reaction channels have been verified.

Key words: Vinyl, O2, IR emission spectra, Elementary reaction channels
