Wavenumbers of the C=O stretching fundamental in the series of 145 conformers of aromatic α,β-unsaturated carbonyl and arylfurancarbonyl compounds were investigated in terms of Yukawa-Tsuno structure-reactivity equation. The parameters of these correlation were compared with the results obtained using Hammett or Brown equation. The separation and the transmission of normal and resonance substituent effects have been discussed in the individual series.
