本文首次用 ̄1HNMR单谱仪法测定了2-羰基丙酸(吡啶-4-甲酰基)腙烯土双核配合物及稀土自由离子的磁化率,并对双核配合物的磁交换作用进行了初步探讨,结果表明用 ̄1HNMR单谱仪法测量稀土配合物的磁化率简便、可靠,样品用量号古矣法的1%左右。
The magnetic susceptibility of 2-oxo-propionic acid (pyridine-4-formyl) hydradenylenite dinuclear complex and rare earth ions were measured by 1H NMR spectroscopy for the first time, and the magnetic exchange of the binuclear complex was preliminary studied The results showed that the magnetic susceptibility of rare earth complexes was very simple and reliable when using 1HNMR single-spectrometer to measure the magnetic susceptibility of rare-earth complexes. The sample dosage was about 1% of the ancient one.
