Abstract

We compute the radiative association (RA) of Cl\(^-\) with H\(_2\) and D\(_2\). We use potential energy and dipole moment surfaces recently tested by a combined theoretical and experimental study of the pre-dissociation spectrum of these complexes. The RA rates are calculated using a quantum approach based on the driven equations formalism and compared with those obtained for similar systems. An indirect comparison with experiment is also discussed using the three body rates measured recently for this system.
