A similar, at least in spirit, NN-TL water potential was reported by Marx and coworkers. That potential made use of long-range fixed-charged electrostatic interactions, that are damped as usual to avoid the Coulomb singularity, as well as short range repulsive Yukawa potentials. The charges are -0.8 for O and 0.4 for H, exactly the ones in the first generation (1981) fixed charged model, TIP. The properties reported were radial distribution functions and the self-diffusion constant, which are in good agreement with experiment.
