| Abstract
| - In an earlier paper on this subject, it was conjecturedthat if temperatures of H2O and D2O are scaledaccordingto their temperatures of maximum density, then thestructural properties of these two liquids should beveryclosely the same. In this paper it is found that the idea is validfor the densities within the four decimal pointexperimental precision of the D2O data. If thisstructural effect is not taken into account, a comparisonofproperties, such as viscosities or self-diffusion coefficients, ofisotopic liquid water would have a reducedmeaning. Comparing data at the same temperature, as hastraditionally been done, simply gives rise tomisleading isotope effects.
