Fullerene dimers C-120 and C120O undergo oxidation to cation radicals and d
issolution in fuming sulfuric acid. Electron paramagnetic resonance study r
evealed the formation of mono-charged C-120(+) and C120O+, as well as doubl
e-charged C120O2+. EPR spectra and electronic structures of these species a
re discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
