Li-x@C-60: Calculations of the encapsulation energetics and thermodynamics
Li@C-60 and Li@C-70 can be prepared and thus, their calculations at higher levels of theory are also of interest. In the report, the computations are carried out on Li@C-60, Li-2@C-60 and Li-3@C-60 with the B3LYP density-functional theory treatment in the standard 3-21G and 6-31G* basis sets. The computed energetics suggests that Li-x@C-60 species may be produced for a few small x values if the Li pressure is enhanced sufficiently. In order to check the suggestion, a deeper computational evaluation of the encapsulation thermodynamics is carried out.
