Distance in zigzag polyhex nanotorus

Abstract

Graph theory was successfully applied in developing a relationship between chemical structure and biological activity. The concept of distance in graphs is basic in the definition of various topological indices for chemical compounds, which determines some of the physicochemical properties of them. In this paper, we explain a method, using the concept of distance in the graph of zigzag polyhex nanotorus, which enables us to compute different topological indices simultaneously. © 2008 World Scientific Publishing Company.
