Total stress as a topological index

Abstract

In this article, we see the total stress of a graph as a topological index and obtain a formula for computing total stress index oftrees. Also, we prove that total stress index of a graph G is zero iff Gis complete. Further, a QSPR analysis has been carried to demonstratethat total stress index can be used as a predictive measure for physical properties of lower alkanes. Linear regression models involving totalstress index have been presented for some physical properties of loweralkanes.
