Abstract
Polarization measurements in the Raman spectra of molten sodium nitrite have shown that the reorientational line widths of the v1 and v2 bands (both of the A1 symmetry type) of NO2̄ are different. Possible reasons are discussed. Also, the line widths of NO2̄ for various molten nitrites are found to depend on R-4 , the cloasest approach distance in the melt, and on Z, the cation charge number. This dependence agrees with theoretical predictions for the coupling of vibrational and reorientational dephasing caused by ion-dipole interactions.Keywords
