The infrared and proton magnetic resonance spectra of hydroxyl ion and water in a potassium nitrate-sodium nitrite melt

Abstract

The infrared and proton magnetic resonance spectra are reported for OH- and H₂O at low concentration (<2 mol %) in a KNO₃-NaNO₂ melt at 150°C. The spectra indicate the absence of hydrogen bonding and the presence of restricted rotation and translation for OH- but the presence of strong complexing to cations and anions for H₂O.
