A theory of
unimolecular gas reactions in which the rate with which the energized reactant molecule breaks down is treated as a function of the energy
that it contains. The theory assumes that the rate is proportional to the number of ways of distributing
among the internal
degrees of freedom of the reactant molecule, in such a manner that the critical energy
is localized in one particular degree of freedom.
