To shed light on the structure of water at different temperatures, the radial distribution functions (RDFs) of oxygenoxygen, oxygen-hydrogen, and hydrogen-hydrogen pairs have been calculated, as shown in Fig. The first point to note here is that the RDFs as obtained from an NNP at 300 K are in good agreement with the previous results from Ref. 32: g OO (r) tends to agree with experimental observations regardless of a much higher first maximum. (As shown in Fig. in Supporting Information) In general, MP2 is more likely to overbind noncovalent complexes.
