| Abstract | KrF-laser-induced fluorescence from CF2-radicals was investigated during photolysis of CF2C12 and CF2HC1 by 193 nm laserlight. In contrast to other publications, which postulated single-vibronic-level fluorescence, the fluorescence is caused by excitation from four closely situated absorption bands. These fluorescence bands of four series, are assigned to/IB (v, 6 2v, 0) R1A (v, v, 0) transitions with Av 0 and 0 < v < 30. The Franck-Condon factors of the/IB (0, 6, 0) R1A (0, v, 0) transitions, the frequencies of the bending vibration (o9 673 __+ 2cm-1) and the anharmonicity constants x2 -0.94 0.08 cm-1 and x2 -0.44 0.10 cm-1 were more precisely determined. For the first time higher anharmonicity constants are evaluated with x2 + x’12 -3.5 1.0cm-1 and x’22 -0.05 0.02 cm1. |
