Abstract
We have detected rovibrational transitions of the $\nu = 2 \leftarrow 1, \nu = 3 \leftarrow 2$ and $\nu = 4 \leftarrow 3$ hot bands of $SH^{+}$ in the $^{3}\Sigma^{-}$ electronic ground state. The signals were detected with velocity modulation in a high current discharge of He and $H_{2}S$. From the new and earlier data on $SH^{+}$ a set of molecular constants was obtained. On the basis of all available data for the electronic ground state of $^{32}SH^{+}, {^{32}}SD^{+}$ and $^{34}SH^{+}$ we have obtained a potential energy curve as an expansion in the Morse-type variable $y = 1 - \exp[-a(r-r_{e})]$.
