摘要
本文使用铽（Ⅲ）为荧光探针，探讨了吲哚－３－乙酸（ＩＡＡ）、吲哚－３－丙酸（ＩＰＡ）、吲哚－３－丁酸（ＩＢＡ）与铽（Ⅲ）的作用。基于Ｆｏｒｓｔｅｒ偶极－偶极无辐射能量传递机理，推算了结合铽（Ⅲ）与吲哚环的ＩＡＡ、ＩＰＡ、ＩＢＰ的距离，它们分别是７．９７，１０．２９，１２．５６。
The action of Tb 3+ with Indole 3 acetic acid(IAA),Indole 3 propanoic acid(IPA),Indole 3 butanoic acid(IBA) has been investigated by using Tb 3+ as a fluorescence probe to monitor changes in terbium fluorescence.In terms of Forster type dipole dipole non radiative energy transfer,the distances between indole ring of IAA,IPA,IBA and a bound terbium ion were calculated,respectively and found to be about 7.97,10.29 and 12.56.
