## Kinetic and absorptionspectral behaviors of N-merhylthioacridone triplet sugest its utility as a reference and a sensitizer under photoescitation in the visible. The efficiency of sinslet oxygen production as a result of triplet quenchins by osygen is essentially unity in polar and non-polar so

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(
