Molten salts, Raman spectra

Infrared spectra of solid K2NbF7 and spectra of Nb(V) in molten KF-LiF were measured by Fordyce and Baum (1966). The spectra showed bands characteristic of the NbFy ion. Solid K2NbF7 has been shown to contain discrete NbFy ions with C2v symmetry. According to Keller (1963), the Raman spectrum of this salt has bands at 388, 630, and 782 cm Contrary to this, solid CsNbFe, which contains octahedral NbFg, shows Raman bands at 280, 562, and 683 cm ...
