The reasons leading to asymmetry of shape of ν1 (A1) contour of nitrate ion in Raman spectra of lithium nitrate melts are discussed. It is shown that the application of Rothschild - Yao theory gives best agreement between the calculated and experimental spectra. However, physical meaning of some of parameters given in this theory is not clear. For lithium nitrate melt, asymmetry of the shape of vibration contour ν1 (A1) of the nitrate ion can be caused by the inhomogeneity of local structure due to different rates of dynamic interactions between particles of the system.
