As expected, mass transfer from the oxygen to the hydrogen atoms decreases the diffusion coefficient, while mass repartitioning combined with scaling increases the finite-size-corrected diffusion coefficient by a factor of 3.35 with respect to the original TIP3P model. Also, the slope in Figure indicates a significant decrease in water viscosity 31 by a factor of 0.293 consistent with a ratio of 1/0.298 of the extrapolated diffusion coefficients D ∞ (Table ).
