Abstract  The nitrogen-doped fullerene has been obtained by arc discharge between two high-purity graphite rods in the atmosphere of N2 and He, The electron spin resonance(ESR) characteristics of N-doped fullerene have been investigated. The results show that the ESR spectra of N-doped fallerene axe composed of two parts, a paramagnetic signal of N-center and a paramagnetic signal of C-center, For comparing with N-doped fullerene, we have also studied ESR spectra of C60 powder, C60 sublimed film and H-doped C60 film. For C60 powder and H-doped C60 film, their in situ ESR. measurements are carried out at various temperatures, and reasonable explanations are proposed.
