UNIFICATION OF SOME LITERATURE MODELS OF AROMATICITY - CALCULATIONAL AND CONCEPTUAL STUDY OF A SET OF ONE-RING SPECIES

Numerous models have been suggested for the important concept of aroma ticity. In the current study, a set of recently suggested models of ar omaticity/homoaromaticity/anti-aromaticity for one-ring species [e.g. pyridazine, oxazole, tropilidene (cycloheptatriene), 1,4-dithiin, [8]- annulene (cyclooctatetraene)] is shown to have a common mathematical f ramework from which a new, unifying quantitative equation has been der ived. Calculational and conceptual application is made to a well defin ed set of one-ring carbocycles.
