The onset of condensation: Association reactions

Abstract

Association reactions are important in a variety of astronomical regions for increasing molecular complexity and as a prelude to condensation. Theories are presented for the two mechanisms — three-body and radiative — by which association reactions occur in the gas phase. The theory for three-body association is in satisfactory agreement with a variety of laboratory studies. This agreement lends confidence to the idea that both theories can be utilized for association reactions of astrophysical importance.
