Overview

In dissociative recombination, a molecular ion captures an electron and fragments into atoms, molecules or ions. Dissociative recombination plays an important and often dominant role in many low to moderate temperature plasmas found in planetary ionospheres, the interstellar medium, fusion devices, laboratory experiments, and the region near re-entry vehicle heat shields. The process has been studied for over 50 years but many of its mechanisms and those of competing processes are modern. Indeed, the study of dissociative recombination has been a challenge for both experimentalists and theoreticians and many areas of modern chemical physics have been employed to unlock its secrets. This is a comprehensive collection of refereed papers describing the most up-to-date developments in dissociative recombination research. The topics covered include the use of microwave afterglows, merged beams and storage rings to measure rate coefficients and to identify the products and their yields. The molecules studied range in size from the smallest, H2+, to bovine insulin ions. The theoretical papers cover the important role of Rydberg states and the use of wave packets and quantum defect theory to deduce cross sections, rate constants and quantum yields. Several theoretical and experimental papers address the controversial topic of H3+ dissociative recombination and its importance in the interstellar medium. Dissociative recombination studies of other molecular ions in the interstellar medium and in cometary and planetary atmospheres are covered. Ionization is an important competitive process to dissociative recombination and its competition with predissociation and its role in the reverse process of the association of neutral species is presented.
