Sound speeds have been measured for aqueous solutions of the nucleoside thymidine at T = 298.15 K and at the pressures p = (10, 20, 40, 60, 80, and 100) MPa. The partial molar volumes at infinite dilution, \( V_{2}^{\text{o}} \), the partial molar isentropic compressions at infinite dilution, \( K_{S,2}^{\text{o}} \), and the partial molar isothermal compressions at infinite dilution, \( K_{T,2}^{\text{o}} \) \( \{ K_{T,2}^{\text{o}} = - (\partial V_{2}^{\text{o}} /\partial p)_{T} \} \), have been derived from the sound speeds at elevated pressures using methods described in our previous work. The \( V_{2}^{\text{o}} \) and \( K_{T,2}^{\text{o}} \) results were rationalized in terms of the likely interactions between thymidine and the aqueous solvent. The \( V_{2}^{\text{o}} \) results were also compared with those calculated using the revised Helgeson–Kirkham–Flowers (HKF) equation of state.
