Bimolecular Association Reactions

Abstract

By means of classical vibration theory a method is developed for estimating the mean lifetimes of the unstable molecules formed by the reaction of two polyatomic radicals. It is shown that these lifetimes are usually long in comparison with the time between collisions, except for the very simplest radicals. Approximate lifetimes for a number of these unstable molecules are given. From these values the orders of the corresponding association reactions may be predicted.
