Since their discovery in 1985, fullerenes have received the attention of many chemical researchers. Kolesov et al. reported the standard enthalpy of combustion and of formation of crystalline C60 based on calorimetric measurements (V.P. Kolesov, S.M. Pirnenova, V.K. Pavlovich, N.B. Tamm, and A.A. Kurskaya,J. Chem. Thermodynamics 28, 1121 (1996)). In one of their runs, they found the standard specific internal energy of combustion to be -36.0334 kJ g-1 at 298.15 K Compute ∆_cH^o and ∆_fH^o of C60.
