Ml. Japas et al., FRACTIONING OF ISOTOPIC-SPECIES BETWEEN COEXISTING LIQUID AND VAPOR WATER - COMPLETE TEMPERATURE-RANGE, INCLUDING THE ASYMPTOTIC CRITICAL-BEHAVIOR, Journal of physical chemistry, 99(14), 1995, pp. 5171-5175
Data for the fractionation of D/H and O-18/O-16 in water liquid-vapor
equilibrium may be satisfactorily accounted for over the entire temper
ature range of coexistence with a rigorous thermodynamic relation and
the assumption of ideal mixing of the binary isotopic water mixtures.
D/H fractionation is used to clarify why the asymptotic behavior obser
ved for many systems extends over a wide range of temperatures, but is
very narrow for isotopic binary mixtures.
