Abstract
The quantum yields of triplet-state formation of 1,2-benzanthracene, 1,2,5,6-dibenzanthracene, tetracene and 2-naphthylamine have been measured using the effect of organometallic compounds as dimethylmercury, tetramethyllead and tetramethyltin on fluorescence intensities and optical densities of triplet to triplet absorption. The quantum yields of triplet state formation of aromatic hydrocarbons can be obtained from the results of flash photolysis experiments only, although the method which involves relative fluorescence measurements is usually preferable especially for viscous solvents or relatively weak heavy atom quenchers.Keywords
