The Relationships Between the π – Electron Energies and Connectivity Indices of Polycyclic Conjugated Hydrocarbons Revisited

The relationship between the π -electron energies (Eπ ) and standard (χ ) and valence (χ ν ) connectivity indices of selected benzenoid and non-benzenoid hydrocarbons is revisited. The initial on the relationship between Eπ and χ and χ ν for polycyclic conjugated hydrocarbons appeared in Refs. 1-3. The new results are found in the revision. 1. D. K. Gupta, P. Singh, Bull. Chem.
