(a) Mean absolute deviations in the total energy relative
to quantum
Monte Carlo reference data calculated using the WHBB and MB-pol many-body
PEFs, the TTM3-F and TTM4-F polarizable force fields, and several
DFT models for configurations (in periodic boundary conditions) extracted
from path-integral molecular dynamics simulations of water performed
with the vdW-DF and vdW-DF2 functionals in ref (251). All data from ref (217). (b) Comparison between
the oxygen–oxygen radial distribution functions calculated
for liquid water in refs (249) and (292) from classical molecular dynamics simulations using the MB-pol many-body
PEF and the BLYP, BLYP-D3, B3LYP-D3 functionals, respectively. (c)
Comparison between the oxygen–oxygen radial distribution functions
calculated for liquid water in refs (249) and (293) from classical molecular dynamics simulations using the
MB-pol many-body PEF and the PBE, PBE+TS(vdW), PBE0, and PBE0+TS(vdW)
functionals, respectively.
