We observe for the 2 M composition that there is a good agreement between experiment and the MD simulations with the polarizable force field. In contrast, the OPLS force field overestimates significantly the solvent-Li pair formation and, correspondingly, underestimates the cation-anion pair formation. Remarkably, via charge rescaling of the OPLS force field the structural agreement becomes even poorer. Thus, for the current example charge rescaling may help to improve the description of dynamical properties but does not help to remedy structural deficiences. Similar conclusions can be drawn for the 1 M composition although the differences are less pronounced. It should also be mentioned in this context that density functional theory calculations suggest that coordination numbers of dimethyl carbonate (DMC) extracted from IR data might be slightly overestimated. Even though DMC and EMC are chemically similar, it is not clear whether this would affect the results in Tab.2. If this was the case, the agreement between experiment and polarizable force field would even improve for 1 M (note that for the higher concentration of 2 M the cluster calculations from Ref. might no longer be representative). Upon varying salt content one finds that until 0.95 M the height of the first peak approximately scales inversely with the salt content. This is equivalent to just a small increase of the CN. In case of infinite strong interaction among the cations and the anions one would expect in the low-concentration limit that the CN is equal to one and the peak of the radial distribution function scales with the inverse salt concentration. This perfect pair-picture would naturally imply that σ d +-/σ N E ≈ 0.5. Indeed, the actually observed value of 0.3 indicates that pair-formation is relevant, albeit not as strong as in this theoretical limit. In the limit of zero salt concentration one would expect that finally entropic effects prevail so that the CN should decrease. However, due to the energetic advantage of local charge neutrality this salt concentration is significantly smaller than the lowest concentration, analysed in this work.
