摘要：

The ground-state rotational spectra of ten isotopomers of the carbon monoxide-acetylene dimer are reported and the spectroscopic constants B(O) and D(J) determined in the usual way in a semirigid rotorfit for a linear molecule. The B(O) values are consistent with a simple linear model of the dimer with nuclei in the order OC...HCCH. The failure to observe the isotopomer OC...HCCD in mixtures of CO and HCCD is interpreted in terms of a zero-point energy difference rather than in terms of a nearly free internal rotation of the acetylene subunit.
