Quasi-line benzaldehyde phosphorescence spectra from toluene solutions

Low temperature phosphorescence spectra have been measured for benzaldehyde, acetophenone and benzophenone in toluene glasses. The emission is typical of an nπ∗ triplet. On slow cooling the spectra sharpen and appear to originate from two different crystal sites for which there is a considerable ene...

Summary:Low temperature phosphorescence spectra have been measured for benzaldehyde, acetophenone and benzophenone in toluene glasses. The emission is typical of an nπ∗ triplet. On slow cooling the spectra sharpen and appear to originate from two different crystal sites for which there is a considerable energy difference, ≈350 cm -1 for benzaldehyde.
