摘要:
The gas-phase reaction of Ca and Sr vapors with various thiols and hydrogen sulfide was studied. These reactions produced the metal monothiolates CaSR and SrSR, where R = H, CH3, CH2CH3, etc. Three electronic transitions, C2A' - X2A', B2A" - X2A', and A2A' - X2A', were detected by laser-induced fluorescence. The spectra are consistent with a bent Ca-S-R structure. Some Ca-S and Sr-S stretching frequencies were determined from the spectra.
