Abstract
The vibration-rotation spectrum of the HSO radical is being studied by the LMR technique in the $10 \mu m CO_{2}$ laser region. HSO is produced in a flow system by reacting $CH_{3}SH$ with the products of a discharge in $O_{2}$. Previous studies of visible chemiluminescence $spectra^{1}$ indicated that two bands of HSO should fall in the $10 \mu m$ region: $\upsilon_{3}$ at $1013 \pm 5 cm^{-1}$ and $\upsilon_{2}$ at $1063 \pm 15 cm^{-1}$. We have assigned a number of transitions belonging to the former band, and find the band origin to be $\upsilon_{3} = 1009.36 cm^{-1}$. Many LMR lines at higher frequencies $(1020 to 1080 cm^{-1})$ have also been recorded. Their assignment is complicated by the presence of LMR spectra of the SO molecule in this region, and by the presence of Coriolis interactions between the (010) and (001) vibrational states of HSO.
