Abstract

The two-state approach to the structure of water is applied to D ₂O. Over the temperature range 4° to 100°C, the molar volume of both the close and open-packed structures is estimated to be approximately the same in D₂O as in H₂O. The enthalpy difference between the two structures is found to be -2915 cal/mole in D₂O compared to -2547 cal/mole in H₂O, indicating an increase in the hydrogen-bond strength of D₂O compared to that of H₂O. Estimates of the relaxational thermodynamic parameters of D₂O are obtained. Only those which depend on the enthalpy difference exhibit an appreciable change from the corresponding parameters in H₂O.
