It is to be assumed that the forces in a molecule are approximately invariant for an isotopic change in mass. Consequently the x-ray diffraction curves for H2O and H2/2O, determined by the structure of the corresponding liquid, may be expected to be nearly alike. Experiment by x-ray diffractions shows this to be the case, for the differences are well within experimental error and are not as much as 1% over the greater part of the diffraction-intensity-angle curves.
