The paper presents the stages of development of photonics of molecules at Tomsk State University. Student of Academician A.N. Terenina - N.A. Since 1935 Prilezhaeva stood at the origins of the birth and development of domestic photochemistry, laid the foundation for the Tomsk school of spectroscopists, the only one beyond the Urals at that time. Research in the field of molecular spectroscopy and quantum chemistry of complex molecules began in 1950 by a student of N.A. Prilezhaeva - V.I. Danilova, later a professor at TSU. Fundamental questions related to the establishment of a relationship between the spectra, the structure of the electron shell and the physicochemical properties of a number of classes of complex organic molecules were posed and resolved. The generalizations made were of great importance for the theory of molecular spectra and practical application and allowed V.I. Danilova in the 1970-80s. create your own scientific school.

The article presents the results of measuring the luminescence of ambient air and a solution of an organic compound, when they are irradiated with a high-current pulsed electron beam with an average energy of Ee = 170 keV and a duration of 2 ns, formed by the RADAN-303 accelerator. It has been shown that under the action of UV radiation, the transformation of the Crystal Violet dye is only 2%. The addition of hydrogen peroxide leads to an increase in the phototransformation of the dye. The action of an electron beam on an aqueous dye solution is accompanied by a decrease in the intensity of air luminescence bands with an increase in the number of irradiation pulses. The results showed the degradation of both the dye itself and its transformation products under the action of an electron beam.
