报道了C2 H3 O自由基的激光诱导单电子振动能级荧光。荧光的0-0带位于28 798 cm−1（347.2 nm）。基态的C-O和C-C伸缩振动能和C-C-O弯曲振动能分别为1560、1150和530 cm-1，激发态的分别为872、1110和432 cm-1。激发态寿命为0.8 μsec。C_2H_3O的双键性质在基态时主要表现为C-O键而不是C-C键。C2 H3 O自由基存在于C2 H4 +O反应以及CH 3CHO +F反应中。
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.
