Title
The impact of univalent impurities on the efficiency of peroxynitrite formation under photolysis of crystalline alkali nitrates
Abstract

The introduction of the thallium ions (I) into potassium nitrate crystals has been stated to result in the decrease of the quantum yield of peroxynitrite under photolysis (253.7 nm), which is due to lesser efficiency of its formation from the triplet excited state of the nitrate ion symmetry 3E′ than from the singlet one. The introduction of the nitrite ions into alkali nitrate crystals by means of co-crystallization is found out to result in the increase of the quantum yield of peroxynitrite, which is brought about by the increase of free volume in the neighborhood of impurity centers.
