Diffusion at the liquid-vapor interface is both interesting and controversial. The very definition of particles "at" the interface is difficult. The diffusion coefficient will in this case be a diagonal tensor; two of its elements are equal and correspond to parallel diffusion (along the interface), the third one corresponds to normal, or perpendicular diffusion (across the interface). Since the particles are continuously leaving and entering the interfacial region, it is also important to study this dynamical process by, e.g., the residence time.
