Hyperfine spectra will be observed in sequences of vibrational and rotational states in small molecules, such as alkali hydrides, or hydroxides, using a high-resolution molecular beam electric resonance spectrometer. These spectra will provide improved values for hyperfine interaction constants, to be compared with those obtained from theoretical calculations of electron wave functions. Systematic variations of the interactions with isotopic substitution, and between the different alkali halide molecules will be examined. Special emphasis will be given to the rubidium salts for which experimental work has already begun, and for which previous hyperfine studies are minimal. Extension of these studies to molecules such as indium and gallium monohalides will be explored.

使用高分辨率分子束电共振光谱仪，可以在小分子（例如碱金属氢化物或氢氧化物）的振动和旋转状态序列中观察到超精细光谱。 这些光谱将为超精细相互作用常数提供改进的值，以便与从电子波函数的理论计算中获得的值进行比较。 将检查同位素取代以及不同碱金属卤化物分子之间相互作用的系统变化。 将特别强调铷盐，其实验工作已经开始，并且之前的超精细研究很少。 将探索将这些研究扩展到一卤化铟和一卤化镓等分子。
