High-resolution rotational spectra of InF, InCl, and InBr have been measured with a pulsed jet cavity Fourier-transform microwave spectrometer. Samples were prepared by vaporizing In with a pulsed Nd:YAG laser, and reacting the vapour with a precursor gas entrained in the Ne backing gas of the jet. Precise rotational and nuclear quadrupole coupling constants have been obtained for all these molecules, along with the first nuclear spin–rotation constants of InCl and InBr. The hyperfine coupling constants are discussed in terms of the electronic structures of the molecules.
利用脉冲喷射腔傅立叶变换微波光谱仪测量了 InF、InCl 和 InBr 的高分辨率旋转光谱。样品的制备方法是用脉冲 Nd:YAG 激光使 In 汽化,然后使蒸气与喷射器 Ne 背景气体中夹带的前驱气体发生反应。我们获得了所有这些分子的精确旋转和核四极耦合常数,以及 InCl 和 InBr 的第一个核自旋旋转常数。 我们根据分子的电子结构对超细耦合常数进行了讨论。
