The mechanism of fluorescence quenching of anthracene by dimethylmercury, tetramethyllead end tetramethyltin has been examined by fluorescence and flash photolysis measurements. The increased rates OF SI -T, and TI -S6 Intersystem-crossings induced by the heavy-atom molecules are discussed

Measurements of the efficiency of rubrene-sensitized photooxidation of 1,3-diphenylisobenzofuran imply that direct formation of singlet oxygen via oxygen quenching of excited rubrene singlets is inefficient. This contrasts with recent puhlications based upon studies of self-sensitized rubrene photoo
Quenching of aromatic excited singlet states (9,10-dimethyl anthracene, 9,10-diphenyl anthracene and perylene) by nitroxyl radical was studied by flash photolysis and fluorimetrically. It is established that the dominant quenching mechanism is enhanced intersystem crossing in the collision complex w
