where D ∞ is the infinite-size limit, ξ = 2.837297, k B the Boltzmann constant, and η the shear viscosity of the fluid at average temperature T . The viscosity η predicted by each functional approximation is generally not known, and relying on the experimental value 188 was observed not to significantly affect the rescaling of D L to D ∞ 187 . In this regard, theoretical viscosities were computationally derived for SCAN and optB88-vdW . We observed negligible deviations in D ∞ when calculated using either experimental or theoretical viscosities (Table ). However, if a functional is too overstructured, it may predict a larger viscosity, leading to an overestimation of D ∞ when calculated with the experimental (lower) viscosity. Another reliable approach to compare with experiment is to rescale the experimental coefficients D exp ∞ back to D exp L , which is the hypothetical experimental value for a box of size L 189 .
