Research output: Contribution to journalArticlepeer-review


The effect of N-oxidation of a series of polychloropyridines on13C NMR parameters has been studied. It has been established that in N-oxides of polychloropyridines an electric field through-space effect of the N-oxide group predominates in the shielding of the γ-carbon atom compared to the other carbon atoms. A linear correlation between13C NMR chemical shifts and total charge densities calculated by the MNDO method for the carbon atoms of N-oxides of polychloropyridines has been found.
