Ev. Skokan et al., ORIENTATIONAL ORDERING TRANSITION IN SOLID C-60 - DSC, HPLC, AND X-RAY STUDIES, Journal of physical chemistry, 99(43), 1995, pp. 16116-16118
The investigation of the orientational ordering transition in solid C-
60 was carried out using differential scanning calorimetry, X-ray, and
high-performance liquid chromatography methods. A remarkable influenc
e of crystal dimensions on the temperature and heat of the phase trans
ition was observed. The influence of impurities is found to be less si
gnificant, while the slight increase of the lattice parameter after me
chanical grinding of solid C-60 is detected.
