Abstract	This paper presents the results of the investigation of the spectral-luminescent characteristics of 12-oximino derivative of 8-aza-D-homogona-12,17a-dion, its hydrochloride, and their dependences on the concentration. It has been shown that the form and position of the absorption spectrums of 16,16-dimethyl-12-oximino-8-aza-D-homogona-1,3,5(10),13-tetraene-17a-one in all solvents used are independent of its concentration. At the same time, for its hydrochloride in ethanol and water, a strong dependence of the absorption spectrum on its concentration has been revealed. On the basis of the experimental data it has been concluded that in these solvents dimers of investigated substance, whose bonding force is chelate hydrogen bonds, are formed. The investigation of the luminescence has shown that these substances practically do not fluoresce. Only in ethanol and water we managed to register a very weak luminescence, whose excitation spectrum is close to the absorption spectrum.
