Vertex-degree-based molecular structure descriptors of benzenoid systems and phenylenes

Abstract

Several recently published papers report expressions for various vertex-degree-based molecular structure descriptors of benzenoid systems and phenylenes. Herein, the general expression for these descriptors is deduced, and it is shown that a simple and generally valid relation exists between such structure descriptors of phenylenes and their hexagonal squeezes. © 2012 Copyright (CC) SCS.
