Abstract
In the course of a recent 5\,$\mu$m high-resolution infrared study of laser ablation products from carbon-sulfur targets, we have reinvestigated the $\nu_1$ vibrational mode of the linear C$_3$S molecule
complementing significantly the pioneering data originally reported by Takano and coworkers\footnote{S. Takano, J. Tang, and S. Saito 1996, J. Mol. Spectrosc. 178, 194}. In addition, located within the $R$-branch of the C$_3$S vibrational mode, a weak new band is observed which exhibits very tight line spacing. On the basis of high-level quantum-chemical calculations, this feature is attributed to
the linear SC$_7$S species, which stands for the first gas-phase spectroscopic detection of this heavy carbon-sulfur chain.
