Stokes–Einstein Relation in Different Models of Water
S. A. Khrapak, A. G. Khrapak
Abstract
The purpose of this paper is to discuss to which extent a microscopic version of the Stokes-Einstein (SE) relation without the hydrodynamic radius applies to liquid water. We demonstrate that the self-diffusion and shear viscosity data for five popular water models, recently reported by Ando [J. Chem. Phys. 159, 101102 (2023)], are in excellent agreement with the SE relation. The agreement with experimental results is also quite impressive. The limitations on the applicability of the SE relation are briefly discussed.
