Electronic absorption spectra of N-alkyl and N-arylsubstituted 2,4-dinitro- and 2,6-dinitroanilines are discussed in the terms of energy and intensity of the energetically lowest absorption transitions and molecular structure (intramolecular hydrogen bond, sterical effects, hyperconjugation and increase of the π-electronic system of the molecule.
