Studies of intramolecular electronic effects in chloroacetophenones C₆H₅COCH_3‐n Cl_n and p‐ClC₆H₄COCH_3‐n Cl_n by ³⁵Cl NQR

Abstract

35Cl NQR (77 K) spectra for two groups of compounds, C6H5COCH3-,Cl, and p-ClC6H4COCH3-,Cl,, are reported. The frequencies were assigned to individual chlorine atoms in the molecules. Polar effects and mechanisms of conjugation in the molecules are discussed. The influence of the polar carbonyl group on the electronic structure of the molecule and the NQR frequency was studied in detail.
