本文测定了原子簇化合物[Mo_2O_2S_2(S_2)_2]~(2-)的红外和拉曼光谱,并在乙腈溶液中测得其共振拉曼光谱和退偏振比。利用X光晶体结构数据,对此阴离子的伸缩振动作了简化的正则坐标分析计算,所得结果可以帮助分析和归属一些Mo—Fe—S原子簇化合物的振动光谱。
In this paper, the infrared and Raman spectra of [Mo_2 O_2S_2 (S_2) _2] ~ (2-) were measured and their resonance Raman spectra and depolarization ratios were measured in acetonitrile solution. Using the X-ray crystal structure data, the simplified regular coordinate analysis of the stretching vibration of the anion is calculated and the results obtained can help to analyze and assign the vibrational spectra of some Mo-Fe-S cluster compounds.
