Dissociative electronic recombination in astrophysics and astrochemistry
Abstract
The role of dissociative electronic recombination (DER) in the formation of interstellar molecules is discussed, reviewing the results of recent theoretical investigations. Topics addressed include deuterium fractionation and ionization in dense clouds, the cosmological implications of deuterium fractionation, the formation of cyanopolyynes, and the interstellar ketyl radical as a test of the DER theory of Bates (1986 and 1987). The reaction pathways governing the interstellar chemistry of key species are shown in diagrams.
