Abstract

Kekule structures are transformed into the subspace of
their double bonds to yield the correspondilng factor graphs,
orig.inally called submolecules (8. E 1- Bas i 1, Internat. J.
Quantum Chem. 21 (1982) 771). A graiph-theoretical analysis of
factor graphs is presented for certain classes o,f benzeno1i:d
hydrocarbons. Such an analysis led to expressions for .the construction
of sextet polynomials of some types of benzenoid
hydroc·arbons containing as many as ten rings in a few seconds
without drawing any graphs.
