摘要
The magnetic susceptibility of rare earth ions and its binuclear complexes of 2-carbonylpropionic acid (pyridine-4-formyl) hydrazone (H2PPFH) was determined for the first time by 1H NMR Single Spectrometer in this paper. The magnetic exchange interaction was also studied. The results show that the 1H NMR method is convenient, reliable and the amount of sample required in the method is about one hundred of times less than that of Goury's method.
