Abstract :

Van der Waals (vdW) He2 diatomic trapped inside buckminsterfullerene�s, C60, void and preserved its diatomic bonding is itself a controversial phenomenon due to a smallness of a void diameter comparing to the He-He equilibrium distance. Using vdWcorrected density functional approaches (hybrid DFT M06-2X and ORCA package), we propound a computational approach, including smaller fullerenes, C20 and C28, to demonstrate that encapsulation of He2 inside the studied fullerenes exhibits an interesting quantum behavior resulting in a binding at shorter, non-vdW internuclear distances, and develop a computational model to interpret these He-He bonding patterns in terms of Bader�s Atom-in-Molecule theory (AIM). We also conjecture a computational existence of He2@C60 on a solid basis of its theoretical UV absorption spectrum and a comparison with that of C60.
