Abstract

Carbon-Sulfur species represent a good fraction of the chemical content of interstellar gas and dust. The electronic properties of these compounds generate peculiar molecular structure and chemical reactivity. Detected C-S molecules in space span from the simplest diatomic carbon monosulfide to long carbon chain (e.g. C₅Sᵃ) and complex organic (e.g. CH₃CH₂SHᵇ). Sulfur chemistry is also particularly interesting due to the still puzzling “missing sulfur” behaviour away from diffuse interstellar regionsᶜ. In this talk we review some of the current projects undergoing in our laboratories, involving the characterisation of rotational spectra of carbon-sulfur species. Techniques adopted for our study, and here briefly reviewed, comprise absorption spectroscopy in cells and in microwave/millimeter supersonic jet, chirped-pulse broadband and frequency modulation spectroscopy.
