✦ Synopsis

The high symmetry of the C6,, molecule and the symmetry of the cubic lattice site in solid ChO imply that in addition to the known orientational phase transition at 250 K, there is a sequence of transitions at lower T. These transitions correspond to a successive freezing of orientational degrees of freedom. An accumulation of transitions is expected at low T.

C,,,-fullerite is the only known solid [ 1 ] which consists of quasispherical homonuclear molecules. At a transition temperature
