A simple formula for calculating resonance energy of benzenoid hydrocarbons
Macedonian Journal of Chemistry and Chemical Engineering, 2006 The topological resonance energy (TRE) of a catacondensed benzenoid hydrocarbon with h six-membered rings and K Kekulé structures can be calculated by the (approximate) formula TRE = Ah + B + CK e–Dh, where A = 0.136, B = –0.223, C = 0.281, and D = 0.454.
