Enthalpy of formation of C70

Gas-Phase Heat of Formation Values for Buckminsterfullerene (C60), C70 Fullerene (C70), Corannulene, Coronene, Sumanene, and Other Polycyclic Aromatic Hydrocarbons Calculated Using Density Functional Theory (M06 2X) Coupled with a Versatile Inexpensive Group-Equivalent Approach

“…The Δ f H ° g,298 values for C 60 , C 70 , corannulene, coronene, and sumanene calculated/predicted using the protocol described herein are presented in Table along with values calculated/predicted by other investigators. Experimental values for C 60 and C 70 − are presented in Table . The accuracy of calculated and experimental Δ f H ° g,298 values for these compounds is discussed individually and in detail later in the Results and Discussion section.…”

Enthalpies of combustion and formation of fullerene C70 by isoperibolic combustion calorimetry

“…To our knowledge, there are six previous works where the enthalpy of combustion of the C 70 has been measured by macro-bomb or microbomb calorimeters procedure [1][2][3][4][5][6], using masses samples from 9 mg to 260 mg, in about six experiments. In this table for reliable comparison, the uncertainty associated with these results is twice the standard deviation of the mean, except for [4] and [6], where the uncertainty corresponds to a five per cent significance level.…”

“…This is clear in the case of the measurement of the enthalpy of combustion of fullerene C 70 , for which only few values have been provided [1][2][3][4][5][6] since this substance was isolated in macroscopic quantities in 1990 [7].…”
