Algebraic Kekule Structures of Benzenoid Hydrocarbons

An algebraic Kekule structure of a benzenoid hydrocarbon is obtained from an ordinary Kekule structure by inscribing into each hexagon the number of pi-electrons which according to this Kekule structure belong to this hexagon. We show that for catafusenes (but not for perifusenes), there is one-to-one correspodence between ordinary and algebraic Kekule structures.
