In our laboratory, we have generated several mixed alkali dimer and trimer anions including: $NaK-,KRb-,RbC5-,Na2K-$ and $K2Na-$. These were formed by injecting relatively low energy electrons directly into an expanding jet of mixed alkali vapors and argon in the presence of a weak magnetic field. We are presently conducting visible photoelectron spectroscopic studies on several of these species in order to determine their electron affinities, their anion dissociation energies, and the electronic energy splittings of their corresponding neutral dimers and trimers.
