Molecules-in-Molecule Estimation of the Extent of Localization of Kekuléan Substructures in Polycyclic Aromatic Hydrocarbons Academic Article uri icon


  • This article first revises graph-theoretical (local aromaticity and overall molecular) indices, introduced by M. Randi in 1975, for benzenoid hydrocarbons and somewhat improves them for computer enumeration. This goes beyond total Kekul structure enumeration, yielding an index calculation useful for the quantitative estimation of localization of different Kekulan substructures (including ethylene-, benzene-, annulene-, and radialene-units). This may be viewed as a "molecules-in molecule" approach to polycyclic aromatic hydrocarbons within the context of graph theoretical partitioning.
