N2 - The pure rotational spectrum of CuS in its X2Πi ground state has been recorded using direct absorption techniques in the range 140-540 GHz. This radical was produced by the reaction of copper vapour with CS2. Both the v=0 and v=1 states of 63CuS were observed, as well as the 65CuS(v=0) isotopomer. 25, 13, and 8 rotational transitions were recorded for these three species, respectively. Both the Ω=1/2 and Ω=3/2 spin-orbit ladders were observed. Accurate rotational, spin-orbit, and lambda-doubling constants were subsequently determined for these molecules. These data suggest that 3d-sulfides have subtle bonding differences relative to the corresponding 3d-oxides.
