Isothermal depolymerization of the two polymers of C 60 , i.e. of 1D orthorhombic phase (O) and of “dimer state” (DS) have been studied by means of Infra-red spectroscopy in the temperature ranges 383–423 and 453–503K, respectively. Differential Scanning Calorimetry (DSC) has been used to obtained depolymerization polytherms for O-phase and DS. Standard set of reaction models have been applied...
By adiabatic vacuum calorimetry the temperature dependence of heat capacity for crystalline dimer of fullerene C 60 has been determined in the range 6-340K at standard pressure. Between 46 and 56K, a glass-like transition of the dimer, the nature of which is, probably, similar to that described for C 60 , has been found. The results were used to calculate the thermodynamic...
