Abstract:  The substituent effects on the position of the L_a band in the spectra of some monosubstituted and 2,5-disubstituted pyridine derivatives and their benzene analogues as well as the spectroscopic properties of the azaatom are quantitatively discussed in terms of the linear free energy relationships involving new sets of σ_UV,K spectral substituent constants.
