Definition

A relation that links the translational diffusion coefficient D of a spherical particle in a continuum viscous fluid to temperature, fluid viscosity and particle hydrodynamic radius, commonly written as D = kB T / (6 π η r) under conditions of low Reynolds number, no slip at the particle surface and where the particle is large compared with solvent molecules.
