Abstract
The lifetime of excited diphenyl ketyl radicals is lengthened by deuterium substitution. The largest effect is observed by substitution at the hydroxylic position; for example, the lifetimes are 3.9, 4.2, 8.7 and 10.5 ns for (C6H5)2COH, (C6D5)2COH, (C6H5)2COD and (C6D5)2COD, respectively, in toluene or toluene-d8 at room temperature. Deuterium substitution in the solvent has no effect other than providing a different atom for the hydroxylic position in the ketyl radical.
