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.
