Abstract

Degree based topological indices are excellent tools for distinguishing structural isomers. The S index, which is calculated using the fifth power of the degree of each vertex, performs well in molecules where branching strongly affects activity. It is particularly powerful when applied to complex molecular graphs, such as nanotubes, polymer structures, and different corona product graph construction. In this paper, we analyze the S index in various corona product graphs.
