| 摘 要： | 在500-100cm^-^1波段范围内测定了[Cl2FeS2MoS2FeCl2]^2^-簇阴离子的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;确定了包括伸缩、变角、扭曲以及伸缩-伸缩相互作用的16个力常数.最后还讨论了所得结果的合理性和可靠性.

| Abstract: | The Fourier transform (FT) IR spectra of [Cl]2FeS2MoS2FeCl2]2- were measured at 100-500 cm-1. A simplified general valence force field was used in a normal coordinate anal. The calculated frequencies agreed with the observed ones, with a mean deviation of <1.0%, confirming the assignments of the vibrational spectrum. Sixteen force constants including stretching, bending, torsion, and stretching-stretching interactions were obtained. The rationality and the reliability of the results are discussed. |
