Graph theory has various applications in chemistry and molecular structure research, and its importance has been growing continuously. In molecular graphs, points represent the atoms, and lines represent the chemical bonds between atoms. This article is about to show the precise evaluation for topological descriptors based on the degree sum of the neighbors of end vertices for some molecular structures. We derive for Sanskruti index, Neighborhood inverse sum index, Neighborhood Harmonic index, Fifth

index, and Neighborhood second modified Zagreb index for two-dimensional lattice structure of certain Nanotube and Nanotorus.
