Heydari Department of Science, Arak University of Technology, Arak, Iran Journal Article 2014 06 24 Let G be a connected simple (molecular) graph. The distance d(u, v) between two vertices u and v of G is equal to the length of a shortest path that connects u and v. In this paper we compute some distance based topological indices of H-Phenylenic nanotorus. At first we obtain an exact formula for the Wiener index. As application we calculate the Schultz index and modified Schultz index of this graph by using the Wiener index. Finally we compute eccentric connectivity index of this graph Wiener index Schultz index Modified Schultz index eccentric connectivity index H-Phenylenic Nanotorus https://ijmc.kashanu.ac.ir/article_9043_d3e21a0a3a8b343631cc8cf5213944e7.pdf
