Symmetry

The degree of p-electron (de)localization and aromaticity of a series of polybenzenoid hydrocarbons (PBHs) has been analyzed through the π-contribution to the electron localization function (ELFπ) calculated at the B3LYP/6-311G(d p) hybrid density functional theory level The extent of p-electron delocalization in the various hexagons of a PBH was determined through analysis of the
