When a mixture of 85Rb, 85Rb2, and D2 was irradiated by laser light at 5145 or 4880 Å, small visible particles appeared and the fluorescence spectra were observed. By analyzing these spectra, we determined the rotational constants Bv and the centrifugal distortion constants Dv and Hv for the X 1Σ+ and A 1Σ+ states of 85RbD. By considering the isotopic dependence of the Dunham coefficients, we determined various molecular constants of 85RbH whose values were in good agreement with the observed fluorescence spectra of 85RbH excited by laser lines at 4762, 4765, and 4880 Å. The process of RbH formation is discussed.
当 85Rb、85Rb2 和 D2 的混合物受到 5145 或 4880 Å 激光照射时,会出现可见的小颗粒并观察到荧光光谱。通过分析这些光谱,我们确定了 85RbD 的 X 1Σ+ 和 A 1Σ+ 态的旋转常数 Bv 以及离心变形常数 Dv 和 Hv。通过考虑邓纳姆系数的同位素依赖性,我们确定了 85RbH 的各种分子常数,其数值与在 4762、4765 和 4880 Å 激光线激发下观察到的 85RbH 荧光光谱非常吻合。
