对Ln~(3+)(Nd~(3+)、Ho~(3+)、Er~(3+))—乙酰水杨酸(Asal)—二安替吡啉甲烷(DAM)体系的乙醇—水溶液的光度法研究和对固态钕配合物的元素分析确定,三元配合物的组成比为Nd~(3+):Asal:DAM=1:3:1;考查了该配合物的红外、紫外吸收光谱,热稳定性和溶解性;计算了相应配合物的超灵敏跃迁的振子强度,讨论了振子强度的增值与配体数目的关系。
The effect of ethanol on the activity of Ln ~ (3 +) (Nd ~ (3 +), Ho ~ (3 +) and Er ~ (3 +)) - acetylsalicylic acid (Asal) - aqueous solution spectrophotometry and elemental analysis of the solid-state neodymium complex confirmed that the composition ratio of the ternary complex is Nd ~ (3 +): Asal: DAM = 1: 3: 1; UV absorption spectra, thermal stability and solubility were calculated. The oscillator strengths of the supra-sensitive transitions of the corresponding complexes were calculated. The relationship between the increment of oscillator strength and the number of ligands was discussed.
