Formula for Calculating the Wiener Index of Catacondensed Benzenoid Graphs

Andrey A. Dobrynin

Abstract

The Wiener index is a topological index (graph invariant) defined as the sum of distances between all pairs of vertices in a chemical graph. This index is examined for molecular graphs of catacondensed benzenoid hydrocarbons. A simple method for the calculation of the Wiener index is put forward.
