Infrared spectroscopic characterization of the trimethylgallium/arsine adduct
摘要:
The initial reaction product of the (CH3)3Ga/AsH3 system has been studied by infrared spectroscopy. When these two reagents were codeposited into argon and nitrogen matrices, clear evidence of 1:1 complex formation was observed. Vibrational modes shifted 10-50 cm-1 in the complex relative to parent band positions. Band assignments were made by analogy to parent band positions and confirmed by deuterium labeling experiments. The spectra suggest a C3-upsilon structure for the complex, with distinct distortion from planarity of the GaC3 skeleton. Room temperature spectra in a static gas cell gave evidence for existence of the adduct at 295 K, either in the gas phase or condensed in the liquid phase on the windows of the gas cell.

Abstract Microwave spectra of three deuterated arsines have been measured and analysed. For AsD 3 distortion moment transitions have been observed for the first time, in the form of the K = ±1 ← ∓2 cluster; their frequencies have been combined with those of previously observed “normal” transitions to give rotational, centrifugal distortion, and 75 As hyperfine constants. For AsH 2 D and AsHD 2 , the
摘要 对三种氘化胂的微波光谱进行了测量和分析。对于 AsD,首次观察到 3 个畸变矩跃迁,其形式为 K = ±1 ← ∓2 簇;它们的频率与之前观察到的“正常”转变的频率相结合,产生旋转、离心畸变和 75 As 超精细常数。对于 AsH 2 D 和 AsHD 2 ,测量已大大扩展,现在首次包括 R 分支跃迁;已经评估了类似的光谱常数。这些数据已与 AsH 3 的早期结果以及谐波力场分析中的振动数据相结合。基态平均 ( rz ) 和平衡 ( re ) 结构均已估计。
