Abstract: Using a recently developed technique for the calculation of the Wiener number (W) of benzenoid systems, we determine explicit expressions for W for several homologous series of pericondensed benzenoid hydrocarbons. An elementary proof for the correctness of the used method is also included.Keywords: mathematics, chemical graph theory, distance in graphs, Wiener number, benzenoidsPublished in DKUM: 05.07.2017; Views: 1455; Downloads: 170 Full text (16,93 MB)This document has many files!

Abstract: Recently introduced algebraic Kekulé structures (AKS) describe the ▫$\pi$▫-electron distribution within rings of a conjugated network. The ratio of the AKS countto the classical Kekulé structures count was studied in benzenoid rotagraphs. By considering three representative classes of such rotagraphs, it was shown that this ratio tends towards either 1 or 0, or its value lies between 0 and 1.Keywords: Kekulé structures, Kekulé structure count, geometric and algebraic Kekulé structures, benzenoids, rotagraphPublished in DKUM: 05.07.2017; Views: 1230; Downloads: 101 Full text (202,56 KB)This document has many files!
