Radical cations of both chlorotrifluoroethylene and bromotrifluorocthylene produced by y-irradiation of solid solutions of halocarbon matrices were detected and identified by ESR. The experimental spin density distributions strongly suggest that these radical cations have a planar structure with the

β¦ Synopsis
EPR spectra attributable to the halogenotrifluoroethylene radical anions have been generated by electron attachment in solid soiutions at Iow temperatures. The spin density distrtbution in these rdids strongly suzeststhat the unpaired electron occupies a (I* orbital. a conclusion which is supported by CNDO/Z calculations.

The anisotropic ESR spectra of the CFsX-radical anions (X = Cl, Br, I) have been observed following 7 irradiation at 77 K of solid solutions containing up to 5 mole % of the CF3X parent compound in tetramethylsilane (TMS), neopentane, and 2-methyltetrahydrofuran. The resolution of the line component
