CMD simulations of periodic cubic systems are carried out using the LAMMPS package . Interparticle interactions are modeled using the extended version of the CL&Pol polarizable force field by Goloviznina et al. based on the OPLS-AA framework. Within this force field the drude oscillator model, implemented in the USER-DRUDE package , is employed to describe all atoms of the system excluding hydrogens. Force field parameters for choline and chloride molecules are taken from the ↵tool package , while parameters for LA molecules are obtained from the OPLS-AA based LigParGen web server . Subsequently, they are polarized analogously to the work by Goloviznina et al. , treating the LA molecule as a single fragment. Electrostatic interactions are computed by the particle-particle particle-mesh scheme with an accuracy of 1⇥10 5 .
