Abstract
Dendrimers are the highly branched organic macromolecules with successive layers or generations of branch units surrounding a central core. In mathematical chemistry, a particular attention has been given to degreebased graph invariant. The NarumiKatayama index and its modified version of a graph G, denoted by NK(G) and NK*(G) are equal to the product of the degrees of the vertices of G. In this work we calculated the NarumiKatayama Indices and its Modified version for some families of dendrimers such as NS1[n], NS2[n] and NS3[n]. The exact formulas of the NarumiKatayama and Modified NarumiKatayama indices of these dendrimers nano structures are presented in this paper.
