Among the diatonic radicals, the alkaline earth monohalides have attracted the interest of many research groups. With their single metal centered electron outside two closed shell ions these radicals represent in same respect a molecular analogon to the alkali atoms. The internuclear distances and potential energy curves are very similar for the electronic ground and first excited states. Hyperfine structure (hfs) arises from the weak interaction of the single electron with the nuclear spin of the halogen nucleus. The heavy species of the group, i.e. strontium and barium monohalides, exhibit particularly complex spectra,and the interpretation became only possible with the help of our recently developed laser-microwave (mw) double resonance methods. The results can only be summarized in this paper.
