FCMs have been applied to a variety of systems, including water clusters, peptides and proteins, Lipids, Carbohydrates, Silicon and Titanium oxides, metal-organic frameworks, and ionic salt clusters. Charge level induction has also been a core attribute to some DFT and semi-empirical based algorithms as well, including the XPol potential method and DFTB (Density Functional Tight Binding). To this date, we have not found a fluctuating charge model specifically tailored towards nucleic acids, and it's worth pursuing whether RNA force fields can also benefit from the same level of improved accuracy as the aforementioned applications have.
