Since their discovery in 1985, fullerenes have been the subject of much researcher, with functionalized c60 being explored for making better solar cells. kolesov et al. reported the standard enthalpy of combustion and formation of crystalline c60 based on calorimetric measurements (v. p. kolesov et al., j. chem. thermodynamics 28, 1121( in one of their runs, they found the standard specific internal energy of combustion to be -36.0334 kj/g at 298.15 k. compute dh0combustion and dh0f per mol of c60 at this same temperature
