摘要：

Rotational transitions were measured for five isotopomers of HCCH-CO using a Flygare-Balle type microwave spectrometer. The observed spectrum is consistent with a linear, hydrogen-bonded HCCH-CO structure. Measured rotational constants in MHz, are B = 1397.370(1) for HCCH-CO, 1394.963(1) for HCCD-CO, 1385.142(1) for HCCH-(CO)-C-13, 1331.23(1) for DCCH-CO and 1329.684(2) for DCCD-CO. The measured rotational constants were fit to obtain a center-of-mass separation for HCCH-CO of R(c.m.)* = 5.018 (7) angstrom. Distortion constants were obtained and analyzed to obtain a force constant and estimate the dissociation energy.
