β¦ Synopsis
Careful diffraction studies reveal that the orientational distribution of C60 molecules in disordered high-temperature FCC fullerene deviates significantly from random. These studies show that the molecular orientational preferences anticipate the low temperature orientationally ordered phase, help explain the orientational glass behavior noted in this material and provide quantitative estimates of the intermolecular orientational forces at work.

Based on the cohesive energy per molecule in fcc solid C 60 , the van der Waals potential is obtained by the use of the Mo bius transform formula. It is found that the calculated van der Waals potential can be fitted by a Morse potential with proper parameters. Different from the previous works, thi
