Sumario:Title screen
Photolysis of crystalline alkali nitrates has been studied using optical, IR, and EPR spectroscopy and chemical analysis of the aqueous solutions of the exposed samples. Excitation of the nitrate ion to 21 E1 | (a1 | e| ) state by exposure to light with wavelength of 172 nm at 300K leads to formation of nitrite and peroxynitrite ions. The photolysis at 77K results in formation of fragment NO2, O- , and O3 - radicals. The quantum yields of the nitrite and peroxynitrite ions were calculated. The nitrite ions and peroxynitrite ions are formed in deep layers of the samples. The mechanism of radical formation is connected with photochemical transformations of the nitrate ion in the surface layer of the crystal.
