The molecular beam electric resonance technique has been used to conduct a high precision examination of the hyperfine spectrum of the four isotopomers of RbCl. Coupling constants for the nuclear electric quadrupole interactions, the spin-rotation interactions, the tensor and scalar spin-spin interactions, and a rubidium nuclear octupole interaction, and their dependence on vibrational and rotational states have been determined. The dominant interaction, the rubidium nuclear electric quadrupole interaction, shows a small shift with substitution of the chlorine isotope.
分子束磁共振技术已被用于对氯化铷四种同位素异构体的超精细光谱进行高精度检测。现已确定了核电四极相互作用、自旋-转动相互作用、张量和标量自旋-自旋相互作用以及铷核八极相互作用的耦合常数，及其对振动和转动状态的依赖性。主要相互作用——铷核电四极相互作用，在氯同位素替换时显示出微小的位移。
