| Abstract: | The paramagnetic induced shifts of the coordination compounds of lanthanide with L-histidinc have been measured in weak-acidic condition by XL-200 NMR spectrometer. The induced shifts were separated into compound formation shifts, contact shifts and pseudo-contact shifts. The structures of coordination compounds were simulated based on the pseudo-contact shifts and some structure parameters have thus been obtained. In addition, the magnetic characteristics of lanthanides were discussed in this paper. |
