Publisher Summary This chapter reports some of the significant recent advances, both theoretical and experimental, in the field of reactive molecular scattering made during the 1970s. Most of the attention is devoted to systems of atoms and small molecules. The chapter offers a glimpse of these developments, thus serving as a 1979 footnote (or postscript) to Sir Harrie Massey's great treatise on slow collisions of heavy particles. Several recent reviews deal quite extensively with various aspects of the reactive scattering of neutral particles. The chapter discusses classical trajectory methods and results and focuses on potential-energy surfaces, collisional ionization, and new developments in the transition-state theory. The information-theoretic (IT) approach to molecular reaction dynamics that was introduced 1972 and applied to the codification, compaction, and correlation of a considerable body of experimental (and computer-generated) reactive-scattering data is discussed in the chapter. The chapter describes molecular-beam chemistry, crossed-beam chemiluminescence, and state-to-state chemistry and concludes with a discussion on the influence of different forms of energy upon reactivity and translational thresholds.
