Let G= (V, E) be molecular graph in which the set of vertices and the set of edges of the graph correspond to the atoms of the molecule and chemical bonds, respectively. The Ediz eccentric connectivity index Eξc (G) of G is defined as   ( ) ( ) ( ) v V G v S v  , where S (v) is the sum of degrees of all vertices adjacent to vertex v, and  v is the eccentricity of v. In this paper, we compute the Ediz eccentric connectivity index of Polycyclic Aromatic Hydrocarbons PAHk.
