Conversely, when choline serves as a donor ((c) and (d) in Figure ) interacting with either LAs or other cholines, the underestimation by the original force field is significantly rectified in FF2 and FF3, resulting in an improved agreement with AIMD results. This di↵erence can be attributed again to the correction, which weakens the Ch-Cl interaction and consequently, more choline molecules are available to form H-bonds with other cholines or LAs. This analysis suggests that the tuning of the selected parameters enhances not only the description of their respective H-bond interactions but also improves, on a global scale, the representation of the entire H-bond network.
