Abstract
The pure rotational spectrum of magnesium sulfide has been measured wi th 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 sla te, as well as for the main isotopomer, (MgS)-Mg-24-S-32, in the first excited vibrational state. Mg-25 nuclear hyperfine structure has been observed and the nuclear quadrupole coupling constant, eQq(Mg-25), ha s been determined. A value for the equilibrium bond length has been ob tained.
