经过20多年理论和实验互相促进之后,已经发展了有关镧系元素能级分析的极详细的理论模型。完成了镧系离子在几种不同的基质晶格中的系统晶场计算,并与实验很一致。探索这些模型计算的结果与另一些类型的(其解释对状态本征矢量很敏感的)实验相吻合的程度,是相当有意义的。可以举出很多不同的例子。 After more than two decades of theoretical and experimental work to promote each other, a very detailed theoretical model for the analysis of lanthanide energy levels has been developed. The systematic field calculation of lanthanide ions in several different host lattices was completed and was in good agreement with the experiment. It is quite interesting to explore the extent to which the results of these model calculations agree with those of other types of experiments that explain the state eigenvector sensitivity. There are many different examples.
