Ideally, and in our experience, the correction terms, ∆V n-b , are short-range. This will be the case provided the MB-FF does provide a quantitatively accurate description of the long-range interactions. Polarizable FFs do in principle provide this level of accuracy. As an aside, it is worth noting that this expression can be re-written in the more canonical MB form seen in papers describing the MB-pol potential of Paesani and co-workers. Namely,
