| 摘 要： | 在500—100cm~(-1)波段范围内测定了Cl_3Sb(μ-S)SbCl_3]~(2-)阴离子的Fourier变换红外光谱。采用简化的普遍价力场(SGVFF)进行了简正坐标分析,振动基频的计算值与观测值符合良好,两者平均偏差小于1.0％,证实了振动谱带的归属,确定了相应的力常数。最后讨论了谱带归属问题和所得结果的合理性和可靠性。

Infrared Spectra and Normal Coordinate Analysis of the CCl_3Sb(μ-S)SbCl_3]~(2-) Dianion |
| |
| Abstract: | The Fourier transform infrared spectra of the Cl3Sb(μ-S)SbCl3]2- dianion have been measured from 500 to 100cm-1. A simplified general valence force field is used in a normal coordinate analysis. The calculated frequencies agree fairly with the observed ones, with a mean deviation of less than 1.0%, thus confirming the assignments of the vibrational spectrum, determining the corresponding force constants. The assignmemts of the vibrational Spectrum as well as the rationality and the reliability of the result are discussed. |
