摘　　要：本文研究了Ｎｄ３＋、Ｅｒ３＋与某些α－氨基酸及ｐｈｅｎ的二元和三元配合物在９５％乙醇体系中ｆ－ｆ超灵敏跃迁吸收光谱，计算了超灵敏跃迁峰的振子强度及β、δ、ｂ１／２参数。探讨了α－氨基酸与Ｎｄ３＋、Ｅｒ３＋成键特点以及超灵敏跃迁峰的振子强度与成键的原子数的关系。The absorption spectra of f f hypersensitive transition for the complexes of Nd 3+ or Er 3+ with some α amino acids and 1,10 phenanthroline in 95 % ethanol solution were studied.The oscillator strength ( P ) and the spectral parameters ( β、δ、b 1/2 ) were calculated.The characteristic of the coordinate bonds of Nd 3+ or Er 3+ and α amino acids and the covalent character of the complexes were disscussed.The result of the experiment shows that the oscillator strength ( P ) is related to the numbers of the atoms which form the coordinate bonds.
