摘要

Thermochemical data for fullerenes are relatively very rare owing to usually small amount of the avaialble material. Some thermochemical information has however been derived from gas-phase experiments using the Knudsen cell mass spectrometry method. Equilibraium constants for electron transfer reactions between fullerenes were measured recently and the related standard Gibbs free energy changes derived. However, the second law treatment of the data cannot produce accurate enghalpy terms. The third law treatment can be carried out, however, one crucial presumpition is needed, viz. that the change in the thermodynamic potentials along the considered reactions is negligible.
