Abstract:The fundamental vibrational bending mode $nu_2$ of disulfur monoxide, S$_2$O, and the associated hot band $2nu_2 - nu_2$ have been observed at high spectral resolution for the first time at the SOLEIL synchrotron facility using Fourier-transform far-infrared spectroscopy. This transient species has been produced using a radio-frequency discharge by flowing SO$_2$ over elemental sulfur. The spectroscopic analysis has been performed using an Automated Spectral Assignment Procedure (ASAP) which has enabled the accurate determination of more than 3500 energy levels of the $v_2=1$ and $v_2=2$ vibrational states. In addition to the high-resolution synchrotron study, pure rotational spectra of S$_2$O in the $v_2=1$ and 2 vibrational states were observed in the frequency range 250 -- 500 GHz in a long-path absorption cell.
