Bond-order correlation energies for small Si-containing molecules compared with ab initio results from low-order Moller-Plesset perturbation theory
A. Grassi, G. M. Lombardo, G. Forte +3
The present study of small molecules containing silicon has been motivated by (a) the considerable interest being shown currently in the kinetics and reactivity of such molecules,…
Equilibrium geometries of low-lying isomers of some Li clusters, within Hartree-Fock theory plus bond order or MP2 correlation corrections
A. Grassi, G. M. Lombardo, G. G. N. Angilella +2
In a recent study by Kornath et al. [J. Chem. Phys. 118 (2003) 6957], the Li_n clusters with n=2, 4 and 8 have been isolated in argon matrices at 15 K and characterized by Raman sp…
Stretched chemical bonds in Si6H6: A transition from ring currents to localized pi-electrons?
A. Grassi, G. M. Lombardo, R. Pucci +3
Motivated by solid-state studies on the cleavage force in Si, and the consequent stretching of chemical bonds, we here study bond stretching in the, as yet unsynthesized, free spac…
