我们合成了有机锗化合物的一类重要中间体β-三苯锗基丙酸和β-三苯锗基丁酸 ,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。在这两种化合物的拉曼光谱中 ,30 50 cm- 1( m)、1 0 2 5cm- 1( m)和 61 8cm- 1( m)分属于 Ph- H的伸缩振动、面内弯曲振动和面外扭曲振动。饱和 Ge- C键的振动分别在 594cm- 1和 587cm- 1,同时指出了 Ph- Ge的几种振动所对应的振动频率。在红外光谱中 ,C=O的振动出现在 1 70 9cm- 1( s)和 1 70 5cm- 1( s) ,与饱和碳相连接的 Ge- C振动出现在 61 7cm- 1( w)和 61 7cm- 1( w)。
We synthesized a class of important organic germanium intermediates β-trichlorobenzene and β-trityl-benzophenone butyric acid, measured the Raman and infrared spectra of the compound, the spectral analysis, the main wave number identified The corresponding molecular vibration. In the Raman spectra of these two compounds, 3050 cm-1 (m), 1025 cm-1 (m), and 61 8 cm-1 (m) belong to stretching vibration of Ph- And out of plane torsional vibration. Vibrations of saturated Ge-C bonds are at 594cm-1 and 587cm-1, respectively. At the same time, the vibration frequencies of several kinds of vibrations of Ph-Ge are pointed out. In the infrared spectrum, the vibration of C = O appears at 1 70 9 cm -1 (s) and 1 70 5 cm -1 (s), the Ge-C vibration of saturated carbon appears at 61 7 cm -1 (w) and 61 7cm-1 (w).
