## Abstract ^1^H NMR spectra of 26 substituted chalcones (3βarylβ1 phenylβ2βpropeneβ1βones and 1βarylβ3βphenylβ2βpropeneβ1βones) have been studied. The chemical shifts of the Ξ± and Ξ² protons to the carbonyl group were correlated with Hammett sΜ parameters. To gain information on the effect of the t
