The modern valence bond description of naphthalene
Abstract
Ab initio spin-coupled calculations have been performed which show that the correlatedπ-type electrons in naphthalene are described well in terms of ten distinct, localized, non-orthogonal orbitals, with contributions from various different modes of pairing up the electron spins; we find that the three Kekulé-type structures dominate the wavefunction, and we estimate the resonance energy.
