Perfluoromethyl, perfluoro-tert-butyl, perfluoroneopentyl, and perfluro-tert-pentyl radicals were observed via EPR in x-irradiated perfluoroneopentane and their equilibrium geometries and/or conformations suggested. The hyperfine splitting constants of the observed perfluoroalkyl radicals were compared with their hydrocarbon counterparts and the size of the fluorine hfsc's explained in terms of the effect of fluorine substitution on hyperconjugation.
