Resonating Valence Bonds in Chemistry and Solid State

Abstract

This chapter combines two complementary parts. In the first part, we discuss (largely qualitatively) the relations between the resonance valence bond (RVB) and tight-binding/linear combination of atomic orbitals (LCAO) pictures of the electronic structure using the archetypal example: the π-system of benzene. The second more formal part is devoted to extensions of the RVB ideas to solids. We exemplify these issues by several simple models ranging from the one-dimensional polyene chain – an infinite extension of benzene molecule – through graphene and finish by probably the most spectacular example of the enigmatic quantum RVB state of copper(II) carbodiimide (CuNCN) – the new material, where an assumption of the RVB character of its electronic phases was crucial for explaining its room- and low-temperature physics.
