✦ Synopsis

The pure rotational spectra of MgS and CaS (both in the X 'L+ state) were observed in the frequency region of 200 to 300 GHz by using a source-modulated microwave spectrometer and a high-temperature cell. MgS was produced by the reaction between magnesium vapor and sulfur vapor, while CaS was produced by the reaction between calcium vapor and OCS. Seven rotational transitions were observed for MgS in the ground vibrational state, and 8 to 10 transitions for CaS in the vibrational states of v= 0 to 3. Least-squares analyses of the observed spectral lines yielded the rotational constants and the centrifugal distortion constants for both molecules.
