TRIADS OF FIBONACCI GRAPHS IN MO CALCULATIONS - SOME APPLICATIONS TO CHARGE-TRANSFER COMPLEXES

El-Basil's Fibonaoci triad (FT) method has been utilised to construct the characteristic polynomials of a series of aromatic hydrocarbon rad icals. These, in turn, have been used to calculate graph-theoretically the HOMO energies of a series of methylbenzenes in a hyperconjugative model. From a correlation of the calculated energies with the charge- transfer bands of their pi-type molecular complexes, reasonable values of the hyperconjugative Huckel parameters of the methyl group have be en found. The convenience resulting from the regressive use or FTs has been focussed on.
