pulsed nitrogen laser is appiied for studying the quenching of aromatic hydrocarbons fluorescence by oxygen. In non-polar solvents the process induces intersystem crossing to the triplet state with a quantum yield of unity. Effects of solvent polarity suggest that the interaction between Sl and O2(
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
