The object of the study is a precursor of N-oxyl radicals: oxidation photosensitizer dioxalate 1-hydroxybenzotriazole. The aim of the project is the development of a photochemical approach for spectral studies of the photogeneration of reactive radicals. The method of investigation is optical absorption spectroscopy. The reactive nitroxide radicals were created and tested an optical portable experimental setup based on a series of single-frequency semiconductor sources to conduct research on photoinduced generation processes. Key advantages of the installation: 3 working spectral ranges (ultraviolet, visible and infrared), which makes it possible to choose the excitation wavelength in accordance with the absorption spectrum of the test substance; radiation power density is 5 ? 7.6 mW / cm2; radiation power control; its use in conducting studies using the method of electron paramagnetic resonance spectroscopy.
