Abstract We measure the cis and trans constants3JCO, Hβ and we discuss the effect on them from the structural factors in the13C spectra of 76 conjugated ω-amino, alkoxy-, alkyl-, dialkyl-, phenyl-α-carbonyl-, and α,α-dicarbonyl-containing compounds. We show that the3JCO, Hβ are stereospecific [3JCO, Hβ (cis) 〈Hβ (trans)] in all the studied compounds. On the basis of the stereo-specificity of the constants, we determine the configuration of the trisubstituted α,β double bond in ketones, ketoesters, and imides of different structures.
