The use of the familiar shift reagents Ln(dpm)~ and Ln(fod)s leads to good results if they are used to simplify the spectra; in those cases where the aim of the application of LSR is to establish the structure of molecules, existing LSR cannot be regarded as satisfactory. The value of the use of Ln(dpm) 3 is lowered as a consequence of its comparatively low solubility, which makes it impossible to
如果使用熟悉的位移试剂 Ln(dpm)~ 和 Ln(fod)s 来简化光谱,则会产生良好的结果;在应用 LSR 的目的是建立分子结构的情况下,现有的 LSR 不能令人满意。Ln(dpm) 3 的使用价值由于其相对较低的溶解度而降低,这使得不可能实现高浓度的LSR和测量结构分析所必需的极限位移。Ln(fod)3 的加合物更易溶解。然而,由于形成包含不止一种底物和(或)LSR [i, 5-7] 的复杂加合物,结构研究变得困难。
