Abstract
A 3.89 mg single crystal of fullerene C60 was grown by sublimation and its thermodynamic properties were determined through DSC measurements. The transition temperature and enthalpy are the highest ones that were ever measured (Ttr = (261.4 ± 0.5) K and ΔtrH = (9.0 ± 0.5) kJ mol-1, respectively) and are thought to be near-standard ones. However, it is shown that mechanical grinding smears out the DSC transition peak. Constraints which develop along free (111) surfaces are assumed to be responsible for this phenomenon.Keywords
