The Radial Distribution Functions (RDF) for liquid water relative to the central QM oxygen atom are shown in Fig. . Compared to the experimental data of Ref. 62, we see that the overall solvent structure of liquid water is well reproduced, albeit with some noticeable overstructuring in the first solvent shell compared to experiment. It is well known that such overstructuring arises from the neglect of Nuclear Quantum Effects (NQE), and thus we view the RDFs in Fig. as indicating that BH&HLYP-D3/6-31+G* provides a faithful representation of liquid water's potential energy surface. Furthermore, we see that FlexiBLE has correctly maintained QM/MM separation (indicated by solid red and blue filled areas), without introducing artefacts in the total RDF.
