On the π-Electron Content of Rings in Benzenoid Parallelograms

  • Tomislav Došlić EMAIL logo

We make use of the classical correspondence between Kekulé structures and lattice paths to obtain explicit formulas for the Pauling bond order of edges in benzenoid parallelograms. These formulas are further used to establish the average π-electron content of hexagonal rings in such benzenoids. We then compare this quantity with the atom-based π-electron content of rings, and study the local and the asymptotic behaviour of their difference.
