Computation of the different topological indices of nanostructures

Abstract

In this research study, several topological indices
have been investigated for linear [n]-Tetracene, V- Tetracenic
nanotube, H-Tetracenic nanotube and Tetracenic nanotori. The
calculated indices are first, second, third and modified second
Zagreb indices. In addition, the first andsecond Zagreb coindices
of these nanostructures were calculated. The explicit formulae
for connectivity indices of various families of Tetracenic
nanotubes and nanotori are presented in this manuscript. These formulae correlate the chemical structure of nanostructures to
the information about their physical features.
