Anomalous sorption kinetics of self-interacting particles by a spherical trap

Antonio Raudino, Antonio Grassi, Giuseppe Lombardo +3

In this paper we propose a computational framework for the investigation of the correlated motion between positive and negative ions exposed to the attraction of a bubble surface t…

Molecules in clusters: the case of planar LiBeBCNOF built from a triangular form LiOB and a linear four-center species FBeCN

G. Forte, A. Grassi, G. M. Lombardo +3

Krueger some years ago proposed a cluster LiBeBCNOF, now called periodane. His ground-state isomer proposal has recently been refined by Bera et al. using DFT. Here, we take the ap…

Equilibrium molecular energies used to obtain molecular dissociation energies and heats of formation within the bond-order correlation approach

A. Grassi, G. M. Lombardo, G. Forte +3

Ab initio calculations including electron correlation are still extremely costly except for the smallest atoms and molecules. Therefore, our purpose in the present study is to empl…

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…
