Eccentric Connectivity Index of Nanosheets and Nanotube of SiO₂

Abstract

Chemical graph theory is a field related to Chemistry which is used to predict the behavior of chemical structures. The current trend in Chemical graph theory is evaluating topological indices. They are the numerical descriptors of the molecular structures derived from their corresponding molecular graph. These indices are studied and used in drugs, pharmaceutical research, and other fields. In this paper, the eccentric connectivity index is computed for nanosheets and nanotubes of SiO₂.
