稀土硝酸盐二甲亚砜络合物的振动光谱研究
摘要:
合成了十四个稀土硝酸盐二甲亚砜络合物, 并对其振动光谱进行了系统的研究。对络合物的谱带进行了归属和讨论。对重镧系络合物中S=O伸展振动和Ln—O伸展振动的分裂归因于相同基团间的共振偶合。在络合物中, NO_3基组频1775 cm~(-1)因所属群发生变化而产生了分裂, 并可以此来确定NO_3基在络合物中的配位方式。指认了络合物中Ln—O键伸展振动频率, 其随稀土角动量的变化呈现“斜W”效应。

THE VIBRATIONAL SPECTRA OF RARE EARTH NITRATE COMPLEXES WITH DIMETHYL SULFOXIDE
Abstract:
Fourteen dimethyl sulfoxide complexes of lanthanide and yttrium nitrates were prepared and analysed. The IR and Raman spectra of the complexes were studied systematically. The bands have been assigned and discussed. The S=O and Ln—O stretching vibration modes split in the heavy lanthanide complexes, which was attributed to the resonance coupling of same groups. The group symmetry changing causes the split of nitrate combination frequency 1775 cm~(-1). The coordination mode of nitrate can be identified in the complexes. The Ln—O stretching mode was suggested. The generic form of “inclined W” between the Ln—O stretching frequency and the L-value of rare earthes was discovered.
