The EPR spectra of CH2FC6o and CHF2C6o are presented, and the dominant conformer for each species identified. It is suggested that the equilibrium configurations of fluoromethyl-C6o radicals are determined not by steric effects, but by Coulombic interactions between highly polarizable fluorine atoms

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 are also described, including factors determining the equilibrium configuration over the C~60~ surface of radicals of the general formula XYZCC~60~. The structure of the higher adducts R~3~C~60~ and R~5~C~60~ is mentioned. In the case of H addition to C~70~, four of the five possible isomers of HC~70~ have been identified, but only one of the 2792 isomers of H~3~C~70~ is reported.

The energetics of the loss of C2 units from Cw and C,a has been extensively studied experimentally, but no consensus has yet been reached as to the energy of C2 dissociation from these fullerenes. We have used the Hat-tree-Fock self-consistent field theory and a hybrid of Hartree-Fock and density fu

It is shown by near-IR that the anion radicals C70 and C2o are formed in vacuum by interaction between the fullerenes C70 and 1-amino-3-propanol (AP) and 1,5-diaminopentane (DAP). The temperature dependence of the ESR spectra for the systems C60-AP, CTo-AP and C7o-DAP were studied. At low temperatur
Electron attachment to C6,, and CT0 yields long-lived (i.e. mass spectrometrically observable) anions C, and C% within a remarkably broad energy region (up to 13-14 eV) as already established in a previous experiment. Inspection of the low energy region reveals, however, that electron capture is cha
