Abstract

The Zhang-Zhang polynomial ?(x) is a recently conceived tool in the mathematical apparatus of theoretical chemistry. It combines (in a quantitative manner) the Kekul?- and Clar-structure-based features of benzenoid molecules. It is shown that the topological resonance energy (TRE) can be accurately approximated as TRE ? a??(x)+ b where x?0.5, by which fact a significant insight is gained into the structure-dependence of TRE of benzenoid molecules.
