Abstract

The microwave pure rotational transitions J = 3/2←1/2 and 5/2←3/2 have been measured for gas phase CuO in its X ²Π state, using microwave-optical double resonance. The copper hyperfine structure was observed, and has been analyzed for the first time for the ground state of an orbitally degenerate transition metal-containing molecule in the gas phase. Rotational, lambda-doubling, and magnetic and electric hyperfine parameters have been evaluated; the Fermi contact parameter b_F has been found to be very large and negative. The problem of determining the signs of the "off-diagonal" hyperfine parameters in ²Π electronic states is discussed.
