Abstract

Infrared emission spectra of molten alkali metal nitrates and chlorates were recorded over the frequency interval from 50 to 3000 cm −1 employing a Fourier transform spectrometer. Emission spectra of molten mixtures of NaNO 3 and NaClO 3 also were measured, and the ν 3 mode of NO − 3 ion was observed with solutions containing about 0.1 mole % NaNO 3 . Far infrared spectra of the melts revealed a broad band which progressively shifted to a lower frequency as the mass of the cation increased. The emission spectrum of each salt at a given temperature was recorded in fewer than 2 min and was of comparable or of better quality than previously reported infrared spectra.
