Abstract. The article discusses the results of study for the optical properties (luminescence) of aqueous solutions with low concentrations of lucigenin. One new methodology for the mathematical processing of luminescence spectra is presented. The method to prepare the solutions, which can be used to identify critical points (D.I. Mendeleev's decrement) in the physicochemical properties of aqueous solutions, is considered.

Keywords: lucigenin aqueous solutions, relaxation, D.I. Mendeleev’s decrement
