镧系元素的许多应用都利用了它们的电子自旋弛豫特性。由于Gd3+的驰豫时间相对较长,双电子距离测量是可能的。由于其他稀土元素的驰豫时间要短得多,所以可以对距离进行驰豫增强测量。磁共振成像造影剂利用了S态Gd3+离子的长弛豫时间,而核磁共振位移试剂利用了选定的其他稀土元素的快速弛豫。除了Gd3+和等电子Eu2+离子外,稀土元素的自旋弛豫速度很快,只有在液氦温度范围内才能观察到它们的EPR谱。在这一章中,简要总结了每种稀土元素的电子顺磁共振性质,重点介绍了电子自旋驰豫。
Many applications of lanthanides exploit their electron spin relaxation properties. Double electron-electron measurements of distances are possible because of the relatively long relaxation times of Gd3+. Relaxation enhancement measurements of distance are possible because of the much shorter relaxation times of other lanthanides. Magnetic resonance imaging contrast agents use the long relaxation time of the S-state Gd3+ ion, and NMR shift reagents use the fast relaxation of selected other lanthanides. Other than Gd3+ and the isoelectronic Eu2+ ion, spin relaxation of the lanthanides is so fast that their EPR spectra can be observed only in the liquid helium temperature range. In this chapter the EPR properties of each of the lanthanides is briefly summarized, with an emphasis on electron spin relaxation.
