In this work the classical valence-bond VB theory of the 1930s is recast Ε½ . in a fully ab initio modern form. The basic premises are simply i that valency is associated with singly occupied orbitals on the constituent atoms of a molecule, more Ε½ . tightly bound electrons being assigned to a ''core,
## Abstract Starting from the 1980s and onwards, Valence Bond theory has been enjoying renaissance that is characterized by the development of a growing number of __ab initio__ methods, and by many applications to chemical reactivity and to the central paradigms of chemistry. Owing the increase of
## Abstract The slow computational speed of the generalized valence bond perfect pairing method (GVBβPP) has been an impediment to its routine use. We have addressed this problem by employing a diatomics in molecules Hamiltonian derived from a second quantization perturbation approach. This results
## Abstract **Covalent, ionic, or something new?** A new interpretation of the topology of the electron density at the bond critical point is proposed to characterize covalent, ionic, and chargeβshift bonding from the density point of view (see figure). The topological properties of the density rep
