氮离子注入固体C-60后，在固体C-60中产生了一种新的顺磁缺陷。超精细分裂和同位素效应明确地表明，顺磁中心含有一个氮核。超精细相互作用是各向同性的，其值与自由氮原子的值相当，并且电子系统的自旋为S = 3/2，如原子氮中一样。负责该中心的络合物可溶于甲苯和CS2，并且是稳定的。我们认为该复合物由C-60内的氮组成。
A new paramagnetic defect in solid C-60 was produced by nitrogen implantation in solid C-60 The hyperfine splitting and the isotope effect unambiguously show that the paramagnetic center contains one nitrogen nucleus. The hyperfine interaction is isotropic, its value is comparable to that of the free nitrogen atom, and the spin of the electron system is S = 3/2, as in atomic nitrogen. The complex responsible for this center is soluble in toluene and CS2 and is stable. We suggest that the complex consists of nitrogen inside C-60.
