✦ Synopsis

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 temperature (15-45 K) the ESR spectrum for C~o is similar to that for species with an axially symmetric g-factor. The anisotropy of the signals is averaged out with increasing temperature. The averaged line broadens with further temperature growth, the sharp signal at g = 2.0001 being superimposed on this wide line. The ESR spectrum in the system CTo-AP at 12.5 K may be tentatively described as a superposition of two ESR spectra, namely the ESR of a radical (assumed to be a cation radical) and of C7c,

Electron spin resonance spectra of the fullercne Cso were measured at pressures up to 4 GPa (40 kbar) and under shear &formation at ambient temperature. The ESR signal grows in intensity with pressure. The shear deformation transforms Cso molecules to lower-symmetry structures.
