Laser-induced single vibronic level fluorescence of the C2H3O radical is reported. The 0–0 band of the fluorescence lies at 28 798 cm−1 (347.2 nm). The C–O and C–C stretching, and the C–C–O bending vibrational energies are 1560, 1150, and 530 cm−1, respectively, in the ground electronic state, and 872, 1110 and 432 cm−1, respectively, in the excited state. The lifetime of the excited state is 0.8 μsec. The double bond nature of C2H3O is more dominant in the C–O bond than in the C–C bond in the ground state. The C2H3O radical is found in the C2H4+O reaction, as well as in the CH3CHO+F reaction.
