Miller, John C. published the artcileHeavy atom effects on the triplet lifetimes of naphthalene and phenanthrene, Synthetic Route of 52358-73-3, the publication is Journal of the American Chemical Society (1977), 99(25), 8175-9, database is CAplus.
Heavy-atom effects on triplet decay rates are reported for the 8 monohalonaphthalenes and for 11 monohalophenanthrenes. The decrease in the lifetime with substitution varies with the square of the at. spin-orbit coupling factor for the attached halogen. The position dependence is qual. related to the unpaired spin-d. distribution in the mol. Investigation of the lifetimes of 13 polyhalogenated naphthalenes and phenanthrenes indicate both pos. and neg. deviations from an additive model for heavy-atom effects. Substituent-induced shifts of the O-O band of the phosphorescence spectra are also tabulated.
