摘    要:我们合成有机锗化合物的重要中间体 4-三氯锗基 - 4-甲基 - 2 -戊酮 ( A)、3-三氯锗基 -3,5,5-三甲基环己酮 ( B)、2 -三氯锗基 - 2 -苯基乙基苯基酮 ( C)、2 -三苯基锗基乙基苯基酮 ( D) ,测量了他们的 Raman和 IR光谱并进行了讨论。在化合物 A- D的 Raman和 IR光谱 ,苯环中的 C- H伸缩振动 ,饱和 C- H伸缩振动 ,饱和 Ge- C伸缩振动等特征数据基本一致。C=O伸缩振动在 Raman和 IR光谱中位置基本一致 ,但在红外光谱中均为强吸收带 ,而在 Raman光谱中的峰强度差别则非常大 ,化合物 A、D的峰非常弱 ,而 C的峰则很强 ,化合物 A- C的 Ge- Cl振动均在 390 cm- 1附近出现强峰。

关 键 词:2-三苯基锗基乙基苯基酮  4-三氯锗基-4-甲基-2-戊酮  拉曼光谱  红外光谱

Abstract:Raman and IR spectra of 2 triphenylgermylethylphenyl ketone (compound D), 4 trichlorogermyl 4 methy1 2 pentanone (compound A) and its derivatives (3 trichlorogermyl 3,5,5 trimethly pimelinketone, compond B and 2 trichlorogermy1 2 phenylethylphenyl ketone, compound C) are investigated. The strength of the C=O stretching motion varies drastically according to their structural differences. The peaks of compounds A and D are very weak but those of compound C are very strong. The peaks at 620 cm -1 (m), 598cm -1 (m),623cm -1 (m), and 617 cm -1 (m) are assigned to the stretching vibration of the saturated Ge C bonds of compound A, B, C, and D respectively.
Keywords:Raman spectra  IR spectra  2  triphenylgermylethylphenyl ketone  4  trichlorogermyl  4  methyl  2  pentanone
