The electron density of delocalized bonds (EDDB) applied for quantifying aromaticity. Szczepanik, D. W., Andrzejak, M., Dominikowska, J., Pawełek, B., Krygowski, T. M., Szatylowicz, H., & Solà, M. Physical Chemistry Chemical Physics, 19(42):28970–28981, 2017. Paper doi abstract bibtex In this study the recently developed electron density of delocalized bonds (EDDB) is used to define a new measure of aromaticity in molecular rings. The relationships between bond-length alternation, electron delocalization and diatropicity of the induced ring current are investigated for a test set of representative molecular rings by means of correlation and principal component analyses involving the most popular aromaticity descriptors based on structural, electronic, and magnetic criteria. Additionally, a qualitative comparison is made between EDDB and the magnetically induced ring-current density maps from the ipsocentric approach for a series of linear acenes. Special emphasis is given to the comparative study of the description of cyclic delocalization of electrons in a wide range of organic aromatics in terms of the kekulean multicenter index KMCI and the newly proposed EDDBk index.
