摘要

Absorption and laser-induced fluorescence spectra of copper dibromide in a solid neon matrix are reported. Similar to those for copper dichloride, electronic transitions between the low-lying so-called ligand field states states are forbidden by the u<->g rule, appear as a result of vibronic Herzberg-Teller coupling. The observed transition energies are in good agreement with the adiabatic state energies derived from a recent gas-phase photodetachment study by Wang and co-workers. The matrix study with its much higher resolution yields detailed information about the copper halide electronic states and their bibrational structures.
