EPR of Graphite and Fullerenes

Streszczenie

Analysis of the EPR results for graphite and fullerenes has led to the development of a model for the g-factor in follerene based on the analogy between graphite and fullerene. Pressure dependence of g-factor in C60 powder confirms the validity of this model. 13C hyperfine splitting ofa0.36 mT in pristine fullerene is also reported. The g-factors of C60 −1 and C60 −3 in a solution and in a different K°C60 fullerides are presented. C60 +n states should be described by the spectroscopic splitting factor larger than that of a free spin.
