Abstract

Abstract A modified (symmetry-adapted) method of fragmentation is developed for determination of the number of Kekule structures ( K ) in benzenoids. Trigonal benzenoids are treated in particular. Two kinds are distinguished: (i) those with a central hexagon and (ii) those with a central vertex. The latter class (ii) consists of obvious non-Kekuleans only, while the former (i) contains all kinds, viz. Kekuleans, obvious and concealed non-Kekuleans. A number of combinatorial K formulas for classes of trigonal benzenoids are deduced.
