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…

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…
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…
