(E)‐1‐heteroaryl‐3‐arylpropen‐1‐ones. The 13C chemicalshift values (δC) of the chalcone derivatives were determined in order to find if they correlated with the Hammett σ values. A good correlation, especially for the β‐C for both series, was found for the 13C chemicalshift values (δC) of the chalcone derivatives with the Hammett σ values. The chemicalshift values of the β‐C of the heterocyclic compounds
