报导了水溶液中形成的各种 Ho~(3+)和Er~(3+)络合物的光吸收测量。这些络合物中的配合基就它们的施主(使配位)部分和它们的螯合作用性质而言是不同的,作为溶液 PH 和[Ln~(3+)]:[配合基]浓度比的函数得出了光谱,对各种络合物所得光谱进行了比较,发现一些跃迁的强度对配合基类型和对 Reported the optical absorption measurements of various Ho ~ (3+) and Er ~ (3+) complexes formed in aqueous solution. The ligands in these complexes are different in terms of their donor (make-up) moieties and their chelating properties as solutions pH and [Ln ~ (3 +)]: [ligand] concentration ratio The spectra of various complexes were compared and the intensities of some of the transitions were found for the ligand type and for
