Abstract
Calculations indicate that ion-molecule reactions in gases exhibit marked k inetic isotope effects. Whereas at high temperatures the effects are normal (the lighter molecule reacts faster than the heavier one), at low temperat ures the reversed isotope effect is predicted: a heavier isotopomeric molec ule reacts with an ion faster than the lighter one.
