Vibrational spectra of alkali chlorates and nitrites in crystalline and molten states

Abstract

The infrared and Raman spectra of NaClO₃ and NaNO₂ are reported in crystalline and molten states. The Raman spectra of melts of LiClO₃, KClO₃, AgClO₃, and KKO₂ are also reported. The melts all show well-developed lattice-like vibrations which are quite distinct from the crystalline vibrations both in energy and intensity. The spectra are interpreted on the basis of a lattice-like structure in the melt.
