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(
