Nonplanarity Index for Fused Benzenoid Hydrocarbons
Polycyclic Aromatic Compounds, 2014The sparse data on nonlanarity of fused polycyclic aromatic hydrocarbons (PAHs) is brought into focus with this critical review. The Sander and Wise thickness index is advocated as a quantitative measure of nonplanarity for PAHs. Some rules for determining the relative degrees of nonplanarity are formulated.

Constant-isomer series of benzenoid hydrocarbons
Theoretica Chimica Acta, 1992The constant-isomer series are studied in relation to the periodic table of benzenoid hydrocarbons. General properties of the table are formulated in terms of explicit expressions. In particular a general expression for the formulas (CnHs) of the ground forms of the constant-isomer series was achieved. The numbers of the isomers (cardinalities of CnHs)

Algebraic Kekule Structures of Benzenoid Hydrocarbons
Journal of chemical information and computer sciences, 2004An 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
