The rotational spectrum of the weakly bound complex OCS $CO2$ has been measured using a pulsed beam Fourier transform microwave spectrometer. The rotational constants of the major isotopic form are A-4454.590 MHz, B-1517.743 MHz, and $C-1129.707$ MHz. The molecule is planar: its structure is analogous to the $C2h$ structure of ($CO2)2$ as determined from high resolution infrared spectroscopy by R. E. Miller $etal.1$ Analysis of the spectrum, structure, and dipole moment will be presented.
