[Cl] were computed 270 to compare the distribution for an IL pair where the cation was fitted with the original procedure and one with a cation for which the parameters were obtained with the transfer procedure. In both cases, the distribution is calculated with respect to the carbons of the imidazolium ring and the corresponding anion. Figure shows that large surfaces are observed opposite to the carbon atoms of the imidazolium (Im) ring. This is consistent with the fact that hydrogen atoms in aromatic systems tend to be more electrophilic in resonant systems. The longer alkyl chain bound to C3 can orient toward one face of the ring resulting in preferential interaction of the anion with the opposite face. These results are in agreement with the observations for the aromatic hydrogens in the RDF calculations (see Figure ).
