The kinetic decays of fullerence radical anions produced in the photoinduce
d intramolecular electron transfer inside three C-60 derivatives and the in
termolecular electron transfer between C-60 derivatives and Et3N have been
investigated by means of TRESR method. The half - lives of ESR signals of f
ullerence radical anions are rather structurally dependent either in intram
olecular or intermolecular reaction systems.
