The triplet states of C6,, and C,,, (fullerenes) in solid phase at 3 and 77 K are detected by the time-resolved EPR technique. The observed time-resolved EPR spectra and the time profiles of the transient signals indicate that the geometries of Cw and CT0 are distorted from the soccerball geometry (

The EPR spectra of F&c and four isomers of FC,c are described and discussed. As with H&n, the four isomers of FC,u that are observed are those with fluorine atoms attached to A-, B-, C-or D-type carbon atoms of the Cm molecule.

## Abstract EPR spectra of freeβradical adducts of C~60~ and C~70~ are described and discussed. In the case of addition to C~60~ the prototype radical is HC~60~ or perhaps MuC~60~. The H/Mu hyperfine anomaly in these radicals is explained. The spectra of alkylβC~60~ and fluoroalkylβC~60~ radicals a
