The Radial Distribution Functions of Water as Derived from Radiation Total Scattering Experiments: Is There Anything We Can Say for Sure?

Figure 24

Close-up of the Fourier transform of the EPSR fits (lines) and scattering data (dots) for the oxygen isotope difference data for D2O (top), oxygen isotope difference data for H2O (upper middle), merged D2O neutron data (lower middle), and merged H2O data (bottom). The arrows show the position of the simulated hydrogen bond peak. (a) corresponds to the fits to the H2O data only, while (b) corresponds to fits to the D2O data only.

(a)    Fit to H₂O data

(b) Fit to D₂O data
