Abstract
By means of Fourier transform microwave spectroscopy of a supersonic jet, the pure rotational spectrum of silyl mercaptan, H$_3$SiSH, has been observed for the first time in a low-current dc discharge through a mixture of silane and hydrogen sulfide heavily diluted in neon. The spectroscopic identification was based on predictions from high-level quantum-chemical calculations at the CCSD(T) level of theory in combination with large basis sets performed using the CFOUR suite of programsrgensen, and J. Olsen), and ECP routines by A. V. Mitin and C. van Wullen. for the current version, see http://www.cfour.de.}. In addition to the parent isotopic species, rotation lines of the rare isotopologs H$_3^{29}$SiSH, H$_3^{30}$SiSH, H$_3$Si$^{34}$SH, and D$_3$SiSD have also been observed.
