Abstract

The closed-shell linear chain SiCCO has been generated for the first time in a supersonic expansion by a DC electric discharge of silane, acetylene, and carbon monoxide highly diluted in neon, and it has been probed by Fourier transform microwave spectroscopy in the 5 - 26 GHz frequency range. The spectroscopic constants B = 2624.2202(12) MHz and D-J = 0.235(47) kHz have been determined. With these constants, the radio spectrum of SiCCO can be predicted with an accuracy better than 1 km s(-1) in equivalent radial velocity up to 60 GHz.
