Abstract
The infrared absorption spectra of nitrite and nitrate ions as impurities in potassium chloride single crystals show a fine structure that must be attributed to rotational motions of these ions. Evidence is found for the existence of different groups of nitrite ions that occupy different lattice sites and that are characterized by a varying degree of rotational freedom. No such evidence is found for the nitrate ion for which a librational type of motion is described.Keywords
