Abstract
In this chapter we are concerned with the elementary bimolecular-collision process A + BC → A + B + C (1) i.e., collision-induced dissociation (CID), which plays a basic role in the kinetics of high-temperature gases. It is of special importance in connection with unimolecular decay, relaxation in shock waves and chemical lasers, and three-body recombination, which is the reverse of CID. In recent years molecular beam data(1–6) on chemical systems exhibiting CID have become available. Consequently, the calculation of cross sections for CID has assumed increasing importance. Even so, the state of the art of computing CID cross sections for systems of chemical interest remains relatively undeveloped compared to that of treating inelastic (Chapters 4–13) and/or reactive (Chapters 14–19) scattering. A number of calculations of CID cross sections have, in fact, appeared. These have been based on a variety of methods: statistical (phase-space),(7,8) optical-model,(9) classical-trajectory (quasi-classical),(10–13) semiclassical,(14—19) and quantal.(20–29) As the statistical, optical-model, and semiclassical methods are treated extensively elsewhere in this volume (see Chapters 12, 16, and 19), we shall focus here on quantal techniques. The following chapter deals with quasiclassical treatments of CID.
