Recent independent determinations by X-ray crystallography of the C—C bond lengths in naphthalene and anthracene are shown to agree well. The experimental values agree to about 0-01 Å with both the simple molecular orbital and simple Pauling theories. These theories also make satisfactory predictions for 1.2 : 8.9-dibenzacridine and chrysene (except for the bond most affected by steric hindrance). The agreement between the two theories for aromatic molecules is traced to a correlation of their… Expand

Semiempirical study of isomerism and intramolecular hydrogen bonds in some substituted anthraquinones
Abstract Structural properties and intramolecular hydrogen bonding in several isomers of dihydroxyanthraquinone were investigated by the semiempirical AM1 method. It is shown that the molecule… Expand

X-RAY diffraction studies of crystalline diphenyl have been described by a number of authors1–4 but the bond-distances and bond-angles have not been determined as accurately as in other aromatic… Expand
EMPIRICAL ATOM-ATOM POTENTIAL FOR A NAPHTHALENE CRYSTAL AND TRANSFERABILITY TO OTHER POLYACENE CRYSTALS
Intermolecular potentials for polyacenes are represented by an atom-atom potential approximation using a revised carbon-carbon interatomic potential. The potential has an attraction term with an r-n… Expand

On Perturbation Calculations for the ?-Electrons and their Application to Bond Length Reconsiderations in Aromatic Hydrocarbons
An alternative method for calculating the atom-atom, atom-bond, bond-bond and other polarizabilities in π-electron molecules, originally due to R. D. Brown, is extended to deal with orbital… Expand
Naphthalene and azulene: Theoretical comparison
Ab initio molecular orbital theory has been used to calculate the structure of naphthalene and it has been shown that the inclusion of electron correlation preferentially favors azulene over… Expand
