In our group the main focus is made on the role of quantum effects (e.g. scattering resonances and non-adiabatic couplings) in radiative association. For the solution of dynamical problems we employ time-independent quantum methods, but also trajectory based classical methods. Radiative association of a number of neutral diatomic molecules has been investigated (CN, CO, SiN, SiP, HF, HD, and NaK). At present we are looking towards ionic systems as well as polyatomics.
