Topological index is a numerical graph invariant derived from molecular graph.The atom bond sum connectivity index drew a lot of interest from chemical graph theorists in a short period of time.Nowadays, the degree sum of a vertex's first neighbors is recognized as a useful parameter in chemical graph theory.Keeping these two facts in mind, the neighborhood degree sum based ABS index (N ABS) is put forward in this study.It is defined as
