Aromaticity of Nonplanar Fully Benzenoid Hydrocarbons

open access: yesThe Journal of Physical Chemistry A, 2017
The Clar aromatic sextet theory can provide a qualitative description of the dominant modes of cyclic π-electron conjugation in benzenoid molecules and of the relative stability among a series of isomeric benzenoid systems. In a series of nonplanar fully benzenoid hydrocarbons, the predictions of the Clar theory were tested by means of several ...

Szeged Indices of Benzenoid Hydrocarbons

Polycyclic Aromatic Compounds, 1996
Abstract The Szeged index (Sz) is a recently proposed structure descriptor based on distances between vertices of the molecular graph. Numerous properties of Sz were previously shown to parallel that of the long-known Wiener index (W). We report explicit combinatorial expressions for Sz of a variety of homologous series of benzenoid hydrocarbons ...

On the Energy of Benzenoid Hydrocarbons

Polycyclic Aromatic Compounds, 2021
In chemistry, the energy of a graph is of interest since it can be used to approximate the total π-electron energy of molecules.
