Abstract

Charge distribution on individual carbon atoms of a fullerene molecule Cn depends on the number of atoms it comprises,n. Only C60 has the same charge on all its carbon atoms while other molecules containing fromn=32 ton=84 molecules are characterized by a variety of charge distributions. A neutral C60 molecule is diamagnetic and does not show EPR signal. Charged C60 v molecules, wherev is the valence taking values fromv=-6 tov=+1, show EPR signals for oddv and forv=2 when a fullerene molecule is in the triple state. EPR lines of isolated fullerene ions are narrow in the whole temperature range whereas EPR lines of MexC60 v in ionic compounds MexC60 are wide and their width decreases with temperature. A model of paramagnetic centers and an empirical formula relatingg-factor to valence have been given.
