RUI: Measurement of Hyperfine Interactions in Small Molecules

该奖项提供了一个项目的继续，该项目使用高分辨率的分子束电子共振光谱仪测量小分子(如碱卤化物或氢氧化物)中振动和旋转态序列的超精细光谱。这些光谱将提供改进的超精细相互作用常数的值，并与从电子波函数的理论计算得到的值进行比较。我们将考察与同位素取代的相互作用以及不同的碱卤化物分子之间的相互作用的系统变化。物理专业的本科生将作为同事与教职员工一起工作的各个方面。

This award provides for the continuation of a project to measure hyperfine spectra in sequences of vibrational and rotational states in small molecules, such as alkali halides 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. Undergraduate physics majors will work with faculty as colleagues in all aspects of the work.
