Pure rotational spectra of NaCCH (X(1)Σ(+)) and MgCCH (X(2)Σ(+)) have been recorded in their ground state and v(5) vibrational level, the metal-C-C bend, in the range 315-525 GHz using millimeter-wave direct absorption techniques. This data set complements previous measurements. For NaCCH, rotational transitions were recorded for v(1)(5)=0(0), 1(1), 2(2), 2(0), 3(3), and 4(4) levels, and for the 0(0) states of NaCCD and Na(13)CCH. Transitions originating in the 1(1), 2(0), and 2(2) states of MgCCH were additionally observed. Rotational, l-type doubling, and vibration-rotation parameters have been determined for both species, as well as estimates of the ω(5) bending frequency.
