Valence-shell electron-pair repulsion theory description

In fact, this feature of Laplacian was extensively employed by Bader s atoms in molecules theory at the purely electronic density level in order to quantum rationalize the previous Gillespie s geometrical VSEPR (Valence Shell Electron Pair Repulsion) description of the molecular bonds (Gillespie, 1972 Bader etal., 1988). 

Presents in an unitary quantum theory the various aspects of chemical bonding, from classical description of valence bond and molecular orbital theories to the modem bondonic-bosonic picture of chemical field and interaction, to crystal and ligand field related with symmetry properties and eigen-groups of molecules, to Valence Shell Electron Pair Repulsion-VSEPR model ...
