摘要:

The available experimental data on the vapor pressure isotope effect (VPIE) of BF3are interpreted within the framework of the statistical theory of isotope effects in condensed systems. It is shown that the temperature dependence of the VPIE of10BF3/11BF3observed by Rayleigh distillation experiments cannot be rationalized at all, while the curie obtained by vapor pressure difference measurements seems to be too steep below the boiling point.
