我们合成了β-三氯锗基丙酸及其类似物并测量了该化合物的拉曼光谱和红外光谱 ,经光谱分析 ,指认了主要波数所对应的分子振动。在 A、B、C、D四种化合物的拉曼光谱中 ,Ge- Cl的振动分别出现在 397cm- 1( vs)、40 0 cm- 1( vs)、394cm- 1( vs)、385cm- 1( vs)中 ,而在红外光谱中却无法证明 Ge- Cl键的存在 ,Ge- C键的振动在 Raman光谱中分别在 594cm- 1( w)、62 6cm- 1( w)、634cm- 1( w)、641 cm- 1( w)。在红外光谱中 ,各种极性基团的振动表现的更明显 ,分别出现了 O- H、CH2 、C- O和 C=O的振动峰。
We synthesized β-trichlorogermanylpropionic acid and its analogs and measured the Raman and IR spectra of the compounds. Spectral analysis identified the molecular vibration corresponding to the main wave number. In the Raman spectra of the four compounds A, B, C and D, the vibration of GeCl appears at 397cm-1 vs 404cm-1 vs 385cm- 1 (vs). However, the presence of Ge-Cl bond in the infrared spectrum can not be proved. The vibration of the Ge-C bond in the Raman spectrum is in the range of 594cm-1 (w), 626cm-1 (w) 1 (w), 641 cm-1 (w). In the infrared spectrum, the vibration of various polar groups is more obvious, and the vibration peaks of O-H, CH2, C-O and C = O appear respectively.
