Light scattering from molten lithium fluoride

Isotropic and anisotropic light scattering (Raman) specta of molten LiF at 865°C have been measured. The data are discussed in terms of the interaction-induced polarizability model and molecular dynamics simulations. The systematics of the reduced Raman spectra of the LiX(X= F, Cl, Br, I) melts are examined and an account of the differences is proposed in terms of the structural peculiarities of LiF.
