| 摘 要： | 中文讨论了Ｅｕ、Ｎｄ、Ｅｒ配合物的超灵敏跃迁现象。结果表明：配合物对称性高低与超灵敏跃迁强度大小没有明显联系，而与配位健的共价性密切相关；在影响配合物光谱性质的诸因素中，电子效应尤为重要。

| Abstract: | The absorption spectra of several complexes of Eu, Nd, Er and fluorescence emission spectra of Eu complexes at liquid nitrogen temperature have been mesured in order to obtain reliable information relationg to symmety aroud the Eu. For these complexes no correlation has been found to exist between the weak intensity of hypersensitive transitions and high symmetry or low symmetry and high intensity.The result show that the covalence of complexes may be play a signficant role in the hypersensitity. |
