CONTRA HARMONIC INDEX OF SOME CHEMICAL STRUCTURES

Abstract

Topological indices are numbers connected to the compounds structural formula. There exist various kinds of topological indices. One such degree based topological index is Contra Harmonic Index (CH). CH index of a graph G which is defined as
. In this article, the CH Index of Rectangular Silicate, Dominating Silicate, Chain Oxide and Double Chain Oxide networks are calculated.
