The spectroscopic criteria for the presence of the azo and quinone hydrazone tautomers were obtained by analysis of the data from electronic spectroscopy and quantum-chemical calculation of the derivatives of 1-phenylazo-2-hydroxy-3-naphthanilide and the fixed forms of the tautomers; the ratio of the azo and quinone hydrazone tautomers depends on the polarity of the solvent; in the transition from chloroform to dimethylformamide the content of the azo form changes from 14.6 to 30.1 percent. "Anomalous" changes in the spectra of 1-arylazo-2-hydroxy-3-naphthanilides compared with the spectra of 1-phenylazo-2-naphthol are brought about by the overlap of the long-wave bands of the azo and quinone hydrazone tautomers with the band for charge transfer from the anilide group to the azo or quinone hydrazone system.
