Force fields (FFs) for large molecules, many-atom or many-molecule non-reactive interactions, are pervasive in computational chemistry, biology, and materials. Among these are polarizable force fields with efficient parameterizations, as reviewed recently. Water, in particular, has been the subject of an astonishingly large number (ca. 50) of FFs, including non-polarizable fixed-charge models and polarizable models like TTM3-F, AMOEBA, and MB-UCB. A large set of these FFs has been critically reviewed for their performance across various properties, ranging from cluster binding energies to condensed phase thermodynamic properties. Very recently, 15 water potentials were assessed against high-level ab initio results for the binding energies of water clusters by Herman and Xantheas. Of these, seven are fixed-charge pairwise models, while eight are many-body potentials. Quoting from that paper "The potentials that perform most consistently across the entire n = 2 -25 [cluster size] range include q-AQUA and TTM2.1-F which all give binding energies within 2.5 % of the reference ab initio values." q-AQUA 10 is a recent many-body CCSD(T)-based potential up to 4-body interactions. However, it was also noted that the polarizable TTM2.1-F potential relies on a cancellation of errors of the many-body contributions to the total binding energy. It should be noted that TTM2.1-F is semi-empirical polarizable potential and a member of the TTMn family of sophisticated polarizable water potentials. Of particular interest here are what we term hybrid ab initio-polarizable water potentials. The first example may be the TTM3-F. In this force field, the 2-b interaction was described by an exp-6 functional form in the OO distance, and fit to MP2 calculations. This was followed by the CC-pol potential which, in the original version, was a full dimensional fit to CCSD(T) 2-body energies for rigid monomers and correct long-range electrostatic interactions for higher body terms. The HBB1 potential was the first flexible potential that was a fit to thousands of CCSD(T) energies, using permutationally invariant polynomials (PIPs). Extending these 2-b potentials to ab initio flexible 3-b interaction came soon after that, and the FFs including that interaction are known by the acronyms WHBB and MB-pol. The WHBB and MB-pol potentials were "hybridized" by using the TTM3-F 4 and TTM4-F 12 potentials, respectively, to describe polarization interactions beyond the 3-b level. The details of how these potentials were interfaced to WHBB and MB-pol are different but not of relevance here. These hybrid potentials, which are approaching the first decade of use, have been applied with quantitative accuracy over the entire range of interest from isolated clusters and hydrate clathrates to the condensed phase up to the phase diagram of water. This statement underscores the major goal of such potentials, which is to be general and with transferable accuracy.
