Abstract

Abstract The pure rotational spectrum of magnesium sulfide has been measured with a cavity pulsed microwave Fourier transform (MWFT) spectrometer, as a test of a new laser ablation source. The J= 1–0 transition near 16 GHz has been measured for 4 isotopomers in the ground vibrational state, as well as for the main isotopomer, 24Mg 32S, in the first excited vibrational state. 25Mg nuclear hyperfine structure has been observed and the nuclear quadrupole coupling constant, eQq( 25Mg), has been determined. A value for the equilibrium bond length has been obtained.
