LABORATORY MEASUREMENT OF THE J=1-0 TRANSITION OF COPPER HYDRIDE

The J = 1-0 transitions of (CuH)-Cu-63 and (CuH)-Cu-65 were measured i n the 468 GHz region with a source modulation submillimeter-wave spect rometer. The CuH molecule was generated by sputtering from copper powd er in a DC glow discharge through hydrogen gas. The observed rotationa l transitions show the line broadening caused by the hyperfine structu re due to the copper nucleus (I = 3/2). The central transition frequen cy, the nuclear electric quadrupole coupling constant, and the nuclear magnetic spin-rotation coupling constant were determined for each iso topomer by line-shape simulation.
