Abstract

The paper surveys ongoing computations on endohedral fullerene systems, combining the treatments of quantum chemistry and statistical mechanics. Relative concentrations of four isomers of Ca@C72, six isomers of Ca@C74, nine isomers of Ca@C82, and four isomers of La@C82 are evaluated using the Gibbs energy based on density-functional theory (DFT) computations. The results illustrate the enthalpy-entropy interplay in the systems produced under high temperatures. Approximations for description of the encapsulate motions are analyzed.
