Abstract: The molecular orientational motion models in different regions of temperature have been proposed in solid C60 to study the mechanism of orientational phase transitions.In terms of these models, the temperatures Tc and Tg are calculated for the transition from facecentred-cubic to simple-cubic lattice and the glass transition respectively, which agree well with the results of experiments.

Key words: Solid C60, Orientational phase transition, First-order phase transition temperature, Glassy transition
