The technique of real-time holographic interferometry is used to study free diffusion in a liquid mixture at 25°C. A new mathematical method is derived for determining diffusion coefficients. The results obtained for the KCl-water system from the mathematical method are compared with the results obtained using the mathematical treatment developed by Gabelmann-Gray and Fenichel.
