Using Pauling's Expanded Bond Order Concept in Determination of Bond Lengths in Polycyclic Aromatic Compounds Having Numerous Fixed Single and Double Bonds

摘要

An amended Pauling bond order equation based on the number of Kekule (K) and Dewar (DS) resonance structures is p_(r8) = (K[G - (e_(rs))] + 0.03DS[G - (e_(rs))])/(K[Gi + 0.03DS[G]) which reliably predicts the bond order of conjugated hydrocarbons.
