H atoms and radicals in ..gamma..-irradiated (CF/sub 3/)/sub 2/CHOH and CF/sub 3/CF/sub 2/CF/sub 2/CH/sub 2/OH liquids have been spin trapped with phenyl tert-butyl nitrone. The H adduct yields are comparable to the radical adduct yields in contrast to the nonfluorinated alcohols in which the H adduct yield is only about 10/sup -2/ of the radical adduct yield. The coupling constants in the partially fluorinated alcohols (A/sup N/ approximately 17 G and A/sub ..beta..//sup H/ approximately 10 G) are significantly larger than in the nonfluorinated alcohols (A/sup N/ approximately 15 G and A/sub ..beta..//sup H/ approximately 8 G) and change smoothly with mole fraction of the partially fluorinated alcohols.
