Abstract
The five-atomic linear molecules carbon suboxide, $O=C=C=C=O$, tricarbon oxide sulfide, $O=C=C=C=S$, and carbon subsulfide, $S=C=C=C=S$, are of considerable interest for both spectroscopists and $astronomers^{1}$. Carbon suboxide belongs to the exotic group of quasilinear $molecules^{1}$, while the microwave experiments of $C_{3}OS$ revealed beyond doubt the spectrum of a linear $molecule^{1}$. In the case of $C_{3}OS$ a new high yield $synthesis^{2}$ allows high-resolution study in the infrared region. In order to provide precision data for the assignment of the forthcoming high-resolution infrared spectra we have measured the milimeter wave spectrum of $C_{3}OS$ for molecules in various excited vibrational states. The results of these studies will be discussed within the framework of earlier studies of O=C=C=C=S and recent work on $S=C=C=C=S^{3}$.
