For one specific salt concentration (0.95 M) the sensitivity of the viscosity on the chosen force field is elucidated, see also Fig. (a). Here, η is the lowest for the polarizable force field followed by charge-scaled force field which in turn is lower than the standard OPLS force field. This is fully consistent with the opposite trend, observed for the conductivities above. Fig. (a) displays the molar N-E conductivity and the inverse viscosity against salt concentration for the specific ratio EC:EMC = 24 : 76. In the context of Fig. we already showed that the molar conductivity, the molar N-E conductivity as well as the diffusivity show an exponential dependence on the salt concentration which is proportional to exp(-ρ s /1.5).
