RUI: Measurement of Hyperfine Interactions in Small Molecules

超精细光谱将在小分子（如碱氢化物或氢氧化物）的振动和旋转状态序列中观察到，使用高分辨率分子束电共振光谱仪。这些光谱将提供改进的超精细相互作用常数值，与从电子波函数的理论计算中得到的值进行比较。与同位素取代和不同碱卤化物分子之间的相互作用的系统变化将被检查。将特别强调实验工作已经开始的铷盐，以前的超细研究很少。将这些研究扩展到分子，如铟和单卤化镓，将进行探索。

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.
