Preferred Label : Rice–Ramsperger–Kassel (RRK) theory;
IUPAC acronym : RRK;
IUPAC definition : 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 ɛ that it contains.
The theory assumes that the rate is proportional to the number of ways of distributing
ɛ among the internal degrees of freedom of the reactant molecule, in such a manner
that the critical energy ɛc is localized in one particular degree of freedom.;
