A complete infrared study of the mixed crystal system of NaNO 3 and NaNO 2 is carried out in the region 600—3000 cm —1 at room temperature. The study includes fundamental internal normal vibrations of the NO — 2 and NO — 3 ions. The IR spectra, spectral band shape intensities, combination modes, and frequencies of the internal modes were studied as a function of NO — 3 ion concentration. Special attention is paid to the bending mode, the combination mode, and a symmetric stretching mode.
