Microcanonical rates and products rovibrational quantum state distributions of several unimolecular dissociations, and canonical rates of some bimolecular associations, are discussed from the viewpoint of variational Rice-Ramsperger-Kassel-Marcus (RRKM) theory. The results are compared with the experimental data and with the very useful benchmark theory, phase space theory. A two-transition-state description is discussed for the threshold regions for the products vibrational excitations.
