Description
The isotope effect of pure liquid on vapor pressure is examined, and the vapor pressure ratios of two different isotopes are calculated. Based on the significant structure theory of liquids, the effect of molecular weight and the effect of moments of inertia are dominant in ordinary/trans-d2 ethylene isotopes; the effect of hindered rotational zero-point energy is dominant in trans-d2/cis-d2 ethylene isotopes; and the effect of intermolecular potential difference is found in CH3OH/CH3/OD isotopes. In the isotopes of CH4/CD4, SiH4/SiD4 and GeH4/GeD4, the weight effect decrease in the order of CH4/CD4 SiH4 SiD4 GeH4 GeO4. (author)
