Abstract

The electronic structures and nuclear quadrupole interactions (NQI) of the 19F*(I= 5/2) state of 19F nucleus in solid BF 3 are studied using the first-principles Hartree-Fock-Roothaan procedure including many-body electron correlation effects. The calculated NQI parameters, 19F*quadrupole coupling constant (e 2qQ) and asymmetry parameter η, were found to be in satisfactory agreement with experiment for the solid state system, which gives confidence in the reliability of the calculated electronic structures in the solid and hence the factors found to influence the binding of the molecules in the solid. It was found that the intermolecular binding energy primarily arises from Van der Waals (VDW) interactions between the molecules resulting from intermolecular many-body effects, which counteract the repulsive interactions between the molecules arising from one-electron Hartree-Fock (HF) theory. © 2008 Springer Science+Business Media B.V.
