Abstract The interaction between the various ions in the molten systems NaNO3-NaNO2, LiNO3-NaNO2 and NaNO3-KNO2 has been investigated by Raman, visible and ultraviolet absorption spectroscopy. It is concluded that the interaction between the anions is very weak and that the cations Na+ and K+ are randomly distributed around the nitrate and nitrite anions. The empty orbital level of Na+ (434 nm) in NaNO3-NaNO2 relative to the π level of NO2- is estimated. When small amounts of Li+ are added to the binary sodium melt, an anomalous spectroscopic result is obtained.
