✦ Synopsis

Fluorescence lifetimes of C~KSCH~,O-,'~-,~-DC~H~CII_~, C6HsCD&'C&~CHi, and CeD,CD+ have been me&wed at 77 K in rigid piasses. Very long decay times are obkerwd for aU the radicals. There is a dramatic deuterium af-.' feet upon ring deuceration; alkyl deuteration lengthens the lifetime if :%e phenyl ring is already deutcrated, but other--exhibits a G&t invckc deuterium effect. The oscillator strength uf the 'AZ * 2Bz transition is calculated to be : no larger than 8 X1O-4.

The doublet-doublet fluorescence spectra of benzyl, pmethylbenzyl andpchlorobenzyl radicals were detected in the 450-650 nm region upon the double-pulse (248 nm-+308 nm) excitation of corresponding benzyl chlorides in hexane at room temperature. The respective fluorescence lifetimes were determined
