Sažetak

Basic characteristic and matching polynomials for benzenoid series are given. Their recursion equations allow one to obtain the characteristic and matching polynomials and the number Dewar Resonance Structures (DSs) of very large members not accessible by other means. It is shown that conjugation is a stronger stabilizing effect than aromaticity. The success of topological resonance energy (TRE) as an index of aromatic stabilization energy (ASE) is because changes in conjugation energy (CE) occur in parallel with changes in aromatic stabilization energy. In the absence of ASE, CE becomes decisive.
