摘要：

EPR spectra of dilute solutions of cation and anion radicals produced from a nearly pure C60 sample and samples containing C60 and C70 were recorded at 9.1 GHz, near 3400 G. The measured g-value, which assigned to (C60)+, is 2.0030(2). A series of four resonances were observed for the anion radicals. The measured g-values are 2.0002 (4), 2.0006(2), 2.0009(4) and 2.0014(4). For most cases, narrow resonances with linewidth of 0.2 G or less were obtained with no apparent hyperfine structure. Three of the anion g-values are tentatively assigned to: (C60)- at g = 2.0006, (C60)3- at g = 2.0009 and (C60)5- at g = 2.0014.
