Infrared and Raman Spectra of Polycrystalline NaBF4

Abstract

The infrared and Raman spectra of polycrystalline NaBF₄ and the Raman spectrum of an aqueous solution of NaBF₄ were measured at 298°K in the region above 200 cm⁻¹. With the exception of ${\nu }_3$ , all of the predicted correlation field components arising from multiplet splitting of the BF₄⁻ vibrations were identified in the polycrystalline spectra.
