Abstract:
Refractive indices of a certain molten nitrate mixture measured goniometrically with visible light at nine wavelengths, varied linearly with temperature at a given wavelength. Dispersion phenomenon was also observed at a fixed temperature. Electronic polarizability was determined using the refractive index extrapolated to infinite wavelength and the semiclassical Clausius-Mossotti equation.
