  Following a fairly comprehensive study on popular interaction potentials of
water (Pusztai et al., J. Chem. Phys., 2008, 129, 184103), here two more recent
polarizable potential sets, SWM4-DP (Lamoureux et al., Chem. Phys. Lett., 2006,
418, 245) and BK3 (Kiss et al., J. Chem. Phys., 2013, 138, 204507) are compared
to the TIP4P-2005 water potential (Abascal et al., J. Chem. Phys., 2005, 123,
234505) that had previously appeared to be most favoravble. The basis of
comparison was the compatibility with the results of neutron and X-ray
diffraction experiments on pure water, using the scheme applied by Pusztai et
al. (2008). The scheme combines the experimental total scattering structure
factors (TSSF) and partial radial distribution functions (PRDF) from molecular
dynamics simulations in a single structural model. Goodness-of-fit values to
the O-O, O-H and H-H simulated PRDF-s and to the experimental neutron and X-ray
TSSF provided a measure that can characterize the level of consistency between
interaction potentials and diffraction experiments. Among the sets of partial
RDF-s investigated here, the ones corresponding to the SWM4-DP potential
parameters have proven to be the most consistent with the particular
diffraction results taken for the present study, by a hardly significant margin
ahead of BK3. Perhaps more importantly, it is shown that the three sets of
potential parameters produce nearly equivalent PRDF-s that may all be made
consistent with diffraction data at a very high level. The largest differences
can be detected in terms of the O-O partial radial distribution function.
