摘要：
Quantum chemical calculations of the molecular properties of the UO2(OH)(2) molecule are presented. From the results the thermodynamic properties of this gaseous species have been calculated, and these have been used to re-evaluate the existing literature study on the volatilization of U3O8 in steam, allowing to derive the enthalpy of formation of the UO2(OH)(2) molecule.
