Popis:	— Phosphorescence decay kinetics and emission spectra of some acetophenone derivatives were measured in ether/alcohol and hydrocarbon glasses. Most decay rates observed were a sum of exponentials, and different emission spectra were observed at different intervals in the decay. The observations can be explained in terms of coexistent n, π*, π, π*, and charge-transfer triplets, but solvent shifts in the direction expected for π, π* and charge-transfer triplets were not observed.
