The Eccentricity Version of Atom-Bond Connectivity Index of Linear Polycene Parallelogram Benzenoid ABC5(P(n,n)).

Among topological descriptors, connectivity indices are very important and they have a prominent role in chemistry. The atom-bond connectivity index of a connected graph G is defined as ABC(G) ... where dv denotes the degree of vertex v of G and the eccentric connectivity index of the molecular graph G is defined as ..., where ef ε(v) is the largest distance between v and any other vertex u of G. Also, the eccentric atombond connectivity index of a connected graph G is equal to ... In this present paper, we compute this new Eccentric Connectivity index for an infinite family of Linear Polycene Parallelogram Benzenoid. [ABSTRACT FROM AUTHOR]
