顺磁性镧系金属有机配合物的~1H核磁共振研究

STUDIES ON 1H NMR SPECTROSCOPY OF PARAMAGNETIC ORGANOLANTHANIDE COMPLEXES

<正> 顺磁类的核磁共振研究大多是简单化合物,偏重理论方面的研究,对镧系配合物曾有报道。由于这类样品对空气和湿气极为敏感,在国内外研究顺磁性~1H谱甚少。本文研究了含氯桥的醚基取代环戊二烯镧系配合物二聚体的~1H化学位移,线宽,弛豫时间T_1和磁化率,从中找出了顺磁类有机镧系配合物~1H NMR的规律。

'H NMR spcctroscopy of paramagnetic bis(2-methoxyethylcyclopentadienyl) lanthanide chlorides in solution have been studied. The region of chemical shifts of proton is about 200ppm. The spectra lines of these complexes were broadened and splitting disappeared. T, and susceptibility were measured. The 1H NMR rule of the paramagnetic organolanthanidc complexes was found.
