Visualizing the collapse and clustering degrees together provides a very informative overview on the characteristics of the system at the di↵erent ratios and the di↵erent force field versions considered (see Figure ). All the systems considered provide a very similar structure with FF1 and FF2: the clustering degree is near to one, meaning that almost all the ChCl molecules form part of the same cluster, and therefore, a very strong segregation takes place in the system. The collapse degree can vary depending on the ratio and the particular force field version considered. FF2, due to the correction of the interaction representation via parameterization, predicts lower collapse degrees. In an homologous situation, Maglia de Souza et al detected an artificial phase-separation problem in the 1:2 ChCl:EG system that was corrected by decreasing the value of Cl -OH interactions and therefore strengthening them. In our case, fitting does not a↵ect significantly the long range structural behaviour of our system, which is still oversegregated, even though thecorrected FF2 force field exhibits a modest decrease of the segregation between ions and neutral molecules compared to the original force field.
