The 13 C NMR spectra of eighteen new derivatives of chalcone have been recorded, calculated and fully assigned. The A i , empirical parameters of the styrylketone, p ‐alkoxycarbonylalkyloxystyrylketone and benzoylethylene group were calculated for the prediction of the chemical shifts of substituted benzenes and chalcones.
