摘要：

C-13-NMR was employed to study C60 molecular dynamics in pure C60 crystals prepared by sublimation technique and by evaporation of CS2-solution of C60. The C60 molecular dynamics in the CS2-grown crystal with orthorhombic (OR) structure was significantly changed by heat-treatments. This behavior was assigned to a structural conversion of OR to FCC (face centered cubic) by heat-treatment and also to annealing effect of defects in the crystal. C70 molecular dynamics was also studied in Pure C70 crystal. The C70 molecular rotation was found to be more restricted than those of C60 molecule in the crystals. It was suggested that an anisotropic molecular rotation is dominant below approximately 280K in the time scale of NMR line width (approximately 20musec).
