Abstract:  The substituent effects on the position of the La 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 σUV,K spectral substituent constants.
