Abstract
The $\tilde{A}^{2}\!A^\prime - \tilde{X}^2\!A^\prime$, $\tilde{B} ^2\!A^{\prime\prime} - \tilde{X}^2\!A^\prime$ and $\tilde{C}^2\!A^\prime - \tilde{X}^2\! A^\prime$ transitions of SrSH along with the $\tilde{C}^2\!A^\prime - \tilde{X}^2\!A^\prime$ transition of CaSH have been observed in our laser ablation spectrometer. These species are created via the reaction of strontium or calcium atoms with H$_{2}$S gas entrained in argon. The spectra are then measured at low and high resolution using laser excitation spectroscopy. For each of the observed electronic transitions, at least one $K_{a}$ sub-band has been observed along with the $1-0$ vibrational bands of the M--S stretch (M=Ca or Sr). The results of a preliminary fit of the high resolution data will be presented along with a comparison of the derived spectroscopic parameters for CaSH and SrSH.
