During the past year, radiation chemical and solid-state ESR techniques were combined to generate and characterize novel radical ions. Observations have been made on a variety of metastable organometallic radical cations derived from Group IV B metal alkyls. Matrix interactions have been discovered between radical cations and the Freon solvent. The radical cation formed from ethylene oxide is the ring-opened 2-oxa-trimethylene cation with a symmetrical C/sub 2v/ planar structure. The CF/sub 3/CCl/sub 2/ radical was formed after ..gamma.. irradiation of the CF/sub 3/CCl/sub 3/ (Freon) matrix. Very large long-range proton hyperfine couplings were found in radical cations of carbonyl compounds. The C/sub 8/F/sub 8//sup -/ ion was studied in MTHF glass, using ESR. Two new inorganic radicals, SF/sub 4//sup -/ and SF/sub 4/O/sup -/, were discovered. (DLC)
