Popis: Integrated phosphorescence spectra of meta-bromobenzophenone crystals were measured in the temperature range from 1.6 to 297 K. The spectra were found to contain two series of monomeric bands associated with the stretching mode of the C=O carbonyl at all temperatures. Above 70 K in the red spectral region, a broad structureless band of unknown nature was observed, the center of gravity of which was shifted to red with increasing temperature. The above phenomena and others anomalies can be due to the structural properties of both the molecule and the crystal.
