We report on the first application of microwave optical polarization spectroscopy to a short-lived excited electronic state of a diatomic molecule. Microwave-induced rotational transitions in the A1Σ,v=1 state of BaO were observed via changes in the polarization of a laser-beam pumping optical transitions in the A1Σ−X1Σ(1,0) band. Compared with other microwave optical double-resonance experiments the new technique requires lower laser intensities and yields remarkably reduced linewidths.
