Abstract
Let G be a molecular graph. The Schultz and modified Schultz polynomials are defined as Sc(G, x)= ½ x d ( u , v ) and Sc*( G,x ) = ½ x d ( u , v ) Where du (ordv)denote the degree of the vertex u (orv), respectively. In this paper ,Schultz, Modified Schultz, Hosoya polynomials and their indices for 2,3-dimethyl hexane an isomer of octane are presented.
