Abstract:

The reactions X HD yields XH D, X HD yields XD H where X is He, Ne, Ar, and Kr, were studied in a two-stage mass spectrometer. In these mass transfer reactions, attention was focused on the isotope effect and the XHXD ratio was determined as a function of the kinetic energy of the HD ion in the range 2 to 20 eV. The results were interpreted in terms of complex formation and the conservation of energy and angular momentum. A model is proposed for modifying ion molecule reaction theory to account for the phenomenon in HD where the centerof-mass is not at the center of the bond and the diatomic possesses a rotation about the center-of-mass. This modification produces an energy dependent isotope effect which correlates well with the experimental data. The charge transfer reaction X HD yields X HD was also observed in the Ar and Kr studies. The results are compatible with Masseys adiabatic hypothesis. Author
