Are Conventional Thermochemical Calculations a Viable Alternative to Measurements of Vaporization Enthalpy of Azeotropes? [PDF]

open access: yesMolecules
The majority of the studies of vaporization enthalpy dealt with pure substances. Reports of this quantity for azeotropes were scarce despite that similar experimental methods could be applied in such measurements.

The Ionic Product of Water in the Eye of the Quantum Cluster Equilibrium

open access: yesMolecules, 2022
The theoretical description of water properties continues to be a challenge. Using quantum cluster equilibrium (QCE) theory, we combine state-of-the-art quantum chemistry and statistical thermodynamic methods with the almost historical Clausius–Clapeyron
