Is Stokes-Einstein relation valid for the description of intra-diffusivity of hydrogen and oxygen in liquid water?

In this study, all available data from experiments and molecular simulations for the intra-diffusivities of H₂ and O₂ in H₂O, and for the self-diffusivity of pure H₂O are analyzed to examine the validity of the Stokes-Einstein relation. This analysis is motivated by the significant amount of work...
