Generally, only adjusting Lennard-Jones parameters, vdW parameters or changing the water model are proposed to help with the issue of strong electrostatic interactions . Electronic continuum correction approach can be used to adjust the charges of ions to enhance the ion representation in non-polarizable force fields . This methodology could be partially also employed on proteins, where the charged side chains are relatively distant from the backbone. However, in the case of RNA, the ribose-phosphate backbone is heavily charged and any simple modifications to the point charges would compromise the description of the backbone dihedrals which are directly related to the point charges.
