Chemical master equation unimolecular reaction

Multifrequency Quantum Rice-Ramsperger-Kassel (QRRK) is a method used to predict temperature and pressure-dependent rate coefficients for complex bimolecular chemical activation and unimolecular dissociation reactions. Both the forward and reverse paths are included for adducts, but product formation is not reversible in the analysis. A three-frequency version of QRRK theory is developed coupled with a Master Equation model to account for collisional deactivation (fall-off). The QRRK/Master Equation analysis is described thoroughly by Chang et al. [62, 63]. 

By about 1972 also, we had unearthed most of the salient features of the diatomic dissociation problem [73.A 73.K], and I now had some appreciation of the properties of the master-equation approach to the chemical reaction problem. Consequently, I spent a sabbatical term at the Physical Chemistry Laboratory in Oxford in the autumn of 1972 planning the beginnings of the state-to-state treatment of unimolecular reactions described in the following pages. The unimolecular dissociation...
