Infrared and Raman spectra of solid LiNO2•H2O, LiNO2, NaNO2, KNO2, and CsNO2 are presented and discussed. Pronounced changes in the spectra of LiNO2•H2O during dehydration to anhydrous LiNO2 are interpreted as evidence for an ordered distribution of NO2− ions over two non-equivalent sites (akin to linkage isomerism) in anhydrous LiNO2. The frequencies of the internal modes of the nitrite ion shift to lower values with increasing cation size. Vibrational bands due to nitrate ion present as an impurity are assigned.

Internal Reflectance

Infrared and Raman spectra have been recorded for room-temperature-phase, powdered samples of LiNO3, NaNO3, KNO3, RbNO3, CsNO3, AgNO3, and TlNO3. For the trigonal systems, the nitrate pairs LiNO3, NaNO3 and RbNO3, CsNO3 give almost identical spectra. For the orthorhombic systems, AgNO3 and TlNO3 give similar spectra, whereas that of KNO3 is significantly different. Site and correlation field perturbations are considerably more pronounced in the antisymmetric stretching region (ν3 ca. 1400 cm−1) than in the antisymmetric bending region (ν4 ca. 700 cm−1). Although lifting of the degeneracy of E′ modes was frequently observed, the reported split of the ν4(E′) mode (ca. 716 cm−1) of the aragonite form of KNO3 could not be confirmed. Multiple internal reflectance techniques have been employed to observe the extremely intense ν3(E′) infrared fundamental ca. 1400 cm−1.

Vibration Spectra

Available data on infrared and Raman spectra of S4N4 in solid state and solutions have been verified and completed. On the basis of normal coordinate analysis an attempt has been made to define with more precision the interpretation of vibration spectra of this compound given in earlier reports.

The infrared and Raman spectra of M2[V2O2(O2)4(H2O)]·xH2O and M2[V2O2(O2)4(D2O)]·xD2O (M = N(CH3)4, Cs) were measured. In the region of the vanadium-oxygen stretching vibrations, the spectra were interpreted based on normal coordinate analysis, employing empirical correlations between the bond lengths and force constants.
