The number of Kekult structures for primitive coronoids is studied. The systems have obvious counterparts within a class of hydrocarbons known as cycloarenes. Complete solutions are given for centrosymmetrical primitive coronoids and those with trigonal or hexagonal symmetries. The technique is base
An economical two-vertex elimination method for deciding whether or not a given polyeyclic aromatic hydrocarbon has Kekult structures is suggested. New concepts of convex (concave) vertices, rectangular sets, convex rectangular sets and convex pairs are introduced.
It is known that an alternative algorithm to the Gordon-Davidson algorithm for counting the Kekule valence structures of catacondensed non-branched benzenoid hydrocarbons is a reformulation of the original algorithm. Recently an alternative algorithm [ 1,2] to the Gordon-Davison (GD) algorithm [ 31
