Abstract:	Excess thermodynamic functions of D₂O water have been calculated from the vibrationally decoupled O−D stretching spectra of very dilute solutions of HOD in H₂O. Comparison of the results with reference calorimetric data for water showed a good correspondence for excess heat capacity above the melting point of ice. The excess enthalpy at the melting point also coincides well with latent heat of melting.

Keywords:	Hydrogen bonding heavy water raman spectroscopy thermodynamics
