SolidC60 was stored in NO or O2 under high pressure, and subsequently the molecules of either gas were found to have diffused into the octahedral interstitial sites in its fcc lattice. 13C NMR MAS spectroscopy revealed a primary resonance at 143.7 ppm, accompanied by several minor peaks shifted downfield. Measurement at temperatures from 210 to 300 K indicated a linear dependence of the chemical shifts
