A Study on Face Index of Chemical Graph Structures and Their Derivatives

Abstract

A topological index is a numeric parameter that may describe the biological, physical and chemical properties which are contingent on the structural behaviour of different chemical compounds. In the vast class of topological indices: one of the index is, the face index which has been recently introduced and it assists in predicting the bond energies, the intermolecular forces, the boiling points and densities of different chemical compounds. This paper derives the formulae for the face index of the tadpole, the ladder and the wheel graphs, their subdivision graphs and the line graphs of their subdivision graphs. And briefly analysis their face indices trends.
