Analysis of UV-absorption spectra of several 2,4- and 2,6-disubstituted pyridines conformed their resemblance to the spectra of meta-disubstituted benzenes. Depending on the resonance character of the substituents in the 2- and 4- positions, a varying importance of the resonance interactions between these substituents and the ring nitrogen atom was observed.
