Dependence of Dewar resonance energy of benzenoid molecules on Kekulé structure count

The dependence of the Dewar resonance energy (DRE) on the Kekulé structure count (K) was found to be significantly different from that earlier anticipated. Within classes of benzenoid isomers, the DRE increases either as K for 0.3 or as (ln K) for 2. Both functional dependencies result in approximate expressions for DRE of nearly equal accuracy. Approximations of the form DRE a K + b and DRE a'...

Binary coding of algebraic Kekulé structures of catacondensed benzenoid graphs

The algebraic Kekulé structure of a finite catacondensed benzenoid graph with h hexagons is described by a binary code of length h. The procedure can be reversed, any (algebraic) Kekulé structure can be recovered from its binary code. c © 2007 Elsevier Ltd. All rights reserved.

Binary Coding of Kekulé Structures of Catacondensed Benzenoid Hydrocarbons

An algorithm is described by means of which the Kekulé structures of a catacondensed benzenoid molecule (with h hexagons) are transformed into binary codes (of length h). By this, computer-aided manipulations with, and memory-storage of Kekulé structures are much facilitated. Any Kekulé structure can easily be recovered from its binary code.
