Magneto optical rotatory dispersion studies of simple electrolyte solutions

Abstract

The m.o.r.d. of concentrated aqueous solutions of LiCl, NaCl, KCl, CsCl have been measured in the wavelength range 350–650 nm. The changes in rotation with wavelength are fitted to a one-term Drude equation and the constants of this equation calculated by the Biot–Lowry, the Yang–Doty, and the Heller methods, the last two methods yielding equivalent results. The problems associated with the calculations of the rotation due to the solute are discussed and the results interpreted in terms of the known behaviour of the solutes studied.
