Calculated Diffusivities for Water Isotopologues in Nitrogen, Oxygen, and Air
Values are computed for the dilute-gas diffusivity of water isotopologues in N2, O2, and their mixture at a composition representing air, for standard conditions of 101.325 kPa and water mole fraction approaching zero.  Calculations employ state-of-the-art intermolecular potentials and classical trajectory …
