## Abstract ^13^C NMR spectra of 39 thiophene and furan chalcone analogues in CDCl~3~ solutions are reported. The effect of substituents on the ^13^C chemical shifts in the phenyl and in the 5‐membered rings is discussed. ^13^C NMR shifts are correlated with Hammett parameters and with experimental

## Abstract ^13^C NMR shifts of 54 chalcones and their thiophene and furan analogues are analyzed by principal component analysis. Thus, a mathematical model is derived for the variation of the carbon shifts in each of seven classes. Two component models are found to be adequate by cross‐validation
