Abstract
The possible orientations in solid C60 were studied by using the model of classical molecular interaction. An orientational dynamics' model was developed to calculate the phase transition temperature of the obs erved face-centre-cubic phase to simple-cubic phase. The calculated tr ansition temperature T(c) = 250K, and its pressure dependence dT(c)/dp = 11.4K / 10(8)Pa agrees well with the experiments. Below T(c), the g lassy transition temperature T(g) = 93K was also predicted correctly.
