Abstract : Rayleigh-Brillouin intensity ratios have been measured for a number of aqueous electrolytic solutions as a function of concentration. The calculated and experimental intensity ratios are in agreement within the experimental precision for solutions of alkali metal and alkali earth halides and nitrates at concentrations up to 3 M, thus confirming applicability of simple concentration fluctuation theory for such systems. In solutions of 2-2 sulfates the observed intensity ratios are significantly higher than the calculated values; the descrepancy remains to be explained although pronounced ionic association may be a factor.
