Abstract

Laser excited, dispersed fluorescence spectra have been recorded for a number of bands of the Ã-X̃ electronic transition of CCl2. Analysis of the data yields well defined values for the harmonic and anharmonic constants for the symmetric ground state vibrations. Additional lines are observed at red shifts ≥5000 cm-1 from the origin, which are not assignable in terms of the known X̃ and à state structure. A possible explanation for these transitions would be perturbations of the singlet X̃ structure by the low-lying triplet ã state.
