摘要：

Doublet and triplet magnetic species have been detected and studied by ESR spectroscopy in the pristine fullerene C-60 both in the solid state and in solution. It has been confirmed that the doublet species take origin from a photon-assisted reaction with the molecular oxygen O-2 ofthe air. Anyway, from T-1 relaxation-time measurements and from physical treatment of the samples, it has been established that the doublet species are not really in solution, but they are contained in the bulk of diamagnetic clusters suspended in the employed solvent. The magnetic interaction between the doublet species has also been detected and it allowed to obtain the mean distance between two of the interacting radical ions which are supposed to be (C-60(+))(.) species.
