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 (10[1])(*) mobility, (10[3])Boltzmann’s constant, and temperature according to the Einstein relation. This (10[1])process’s flux equals negative (10[1])a namesake (10[1])coefficient times a (10[1])gradient (10[1])according to (10[1])Fick’s first (10[3])law. This process occurs across a (10[1])semipermeable membrane in osmosis. For (10[1])10 points, name this net movement of molecules from high to low concentration. ■END■
