Remarkably, while the g(r) value of the first peak in the Cl -Cl RDF with the Tang-Toennis damping function approaches that obtained by AIMD, it holds its position at around 500 pm (see supplemetary material). Consequently, the FF3 force field shows no improvement in the positioning of the first neighbor peak. This suggest that our structure relies mostly on Cl -ChOH and Cl -LACOOH interactions, which makes the overall structure less dependant on the polarization e↵ects than other, non carboxylic acid-based systems.
