The attenuation from this phenomenon is calculated with the Stejskal–Tanner equation, which is used in a form of NMR that is named for “ordering” molecules by this process. DLS measures the intensity correlation function to determine a coefficient measuring this process. Mixing two substances that undergo this process at different rates leads to the formation of Turing patterns. A coefficient governing this process equals the product of (*) mobility, (10[1])Boltzmann’s constant, and temperature according to the Einstein relation. This (10[1])process’s flux equals negative a namesake coefficient times a gradient according to (10[1])Fick’s first law. This process occurs across a semipermeable membrane in osmosis. For 10 points, name this net movement of molecules from high to low concentration. ■END■
