Abstract: IR, ¹H  NMR and ¹³C NMR spectra of 3-halo-2,6-dimethylpyridine N-oxides and their 4-nitro derivatives were recorded. The influence of electron properties of substituents on changes of wavenumbers of nu(N⁺-O^-) bands and chemical shifts ¹H  and ¹³C was analyzed. It was found that the ''ortho-effect'' of 2-methyl group inhibits diamagnetism of halogens.
