摘要

在 2932 至 3092 cm-1 区域观察到了 H15NO- 阴离子的旋转分辨振动自分离光谱。观察到 K=4 至 8 的 rRKN 支,以及 K=5 和 6 的两个 rQKN 支。此外,还确定了 H14NO- 的 rQ5N 支。新的观测结果允许对 H15NO- 进行旋转分析,并要求对以前观测到的 H14NO- 光谱进行重新分析。光谱与 rNH=1.099 Å、rNO=1.330 Å 和 ∠HNO=105.5° 的基态 (rm1) 几何结构相一致,与 Ellis 和 Ellison 关于 NO 键长度的研究结果十分吻合,并与最近对这种阴离子的理论处理结果进行了很好的比较。该波段已被重新分配为 0,2,0-(0,0,0) 波段。

The structure and rotationally resolved autodetachment spectrum of H15NO– and H14NO– near 3000 cm−1

The structure and rotationally resolved autodetachment spectrum of H15NO– and H14NO– near 3000 cm−1

The rotationally resolved vibrational autodetachment spectrum of the H15NO anion has been observed in the region from 2932 to 3092 cm-1. rRKN branches were observed for K=4 through 8, and two rQKN branches with K=5 and 6 were assigned. The rQ5N branch of H14NO has also been identified. The new observations have allowed a rotational analysis of H15NO and have required a re-analysis of the previously observed spectrum of H14NO. The spectra are consistent with a ground state (rm1) geometry of rNH=1.099Å, rNO=1.330Å, and HNO=105.5°, in good agreement with the results of Ellis and Ellison for the NO bond length and comparing well with recent theoretical treatments of this anion. The band has been reassigned as the 0,2,0-(0,0,0) band.
