Alkane and olefin radical cations are characterized by time-resolved fluorescence detected magnetic resonance (FDMR) in pulse radiolysis of neat alkane liquids and binary alkane mixtures at room and low temperatures (approx. 180K). FDMR-EPR spectra of the cis-decalin radical cation and the norbornane radical cation are detected a low concentrations (10/sup -3/-10/sup -1/ M) of cis-decalin and norbornane, respectively, in alkane mixtures. Parent minus H/sub 2/ olefin radical cations are observed in neat alkanes and in alkane mixtures. Studies of the temperature and concentration dependences of olefin cation formation suggest that olefin cations originate in the fragmentation of parent alkane cations and that this reaction depends on the energy content of the parent cation. Other possible reactions of alkane radical cations are discussed.
