This is a theory applied to
unimolecular or
bimolecular reactions proceeding through long-lived complexes. The
probability of reaction is assumed to be proportional to the number of states available to a
particular product
channel divided by the number of states corresponding to all product channels. The theory
is used to predict rates, product energy distributions, product velocity distributions,
and product
angular momentum distributions.
