Abstract
A rate expression has been derived for kf, the third order forward rate constant in ion-molecule clustering reactions, by means of an energy transfer mechanism. The rate expression has been tested against all the available data concerning the temperature dependence of such reactions and the predictions as to the effect of cluster size and nature of third body upon the magnitude of kf have been considered. The rate equation appears to provide a useful method for the estimation of kf values to within an order of magnitude.Keywords
