Abstract The interaction between C 60 's in solid C 60 has been calculated by (exp‐6–1) potential, and the cause and the controlled factor of the high rapid rotations of C 60 's were discussed. In order to describe the disordered degree of C 60 rotation, an equivalent M is introduced. The phase transitions at the ∼260 K and at the ∼90 K are studied from the viewpoint of C 60 rotation. The potential barriers of the ordered rotation below the ∼260 K and the disordered rotation above the ∼260 K have been given, and the effect of the external pressure on the temperature of phase transition has also been given.
