摘要作为一种新型激光烧蚀源的测试，用腔式脉冲微波傅里叶变换光谱仪测量了硫化镁的纯转动光谱。测量了4种同位素基态振动态和主要同位素24 Mg32 S第一激发振动态在16 GHz附近的J = 1-0跃迁。观察到了25 Mg核的超精细结构，并测定了核四极耦合常数eQq（25 Mg）。平衡键长的值已获得。
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, 24 Mg 32 S, in the first excited vibrational state. 25 Mg nuclear hyperfine structure has been observed and the nuclear quadrupole coupling constant, eQq ( 25 Mg), has been determined. A value for the equilibrium bond length has been obtained.
