本文合成了除钜、铈外的所有镧系元素和HPMBP(HA)所形成的配合物REA_3(RE表示稀土),并测定了它们的近红外和Raman光谱,对Raman光谱的低波数段的谱峰进行了细致的分析。我们采用了一种简单易行的新方法指定了RE-O键伸缩振动峰的位置,并对13种稀土配合物的RE-O键伸缩振动峰进行了综合分析。对该键的力常数及其力常数和稳定常数的关系也进行了分析。
In this paper, REA_3 (RE is rare earth) was synthesized from all the lanthanides except cerium and cerium and HPMBP (HA), and their near-infrared and Raman spectra were measured. Peak conducted a detailed analysis. We have adopted a new and easy method to specify the position of the stretching vibration peak of RE-O bond and a comprehensive analysis of the stretching vibration peak of RE-O bond of 13 kinds of rare earth complexes. The force constant of the bond and the relationship between the force constant and the stability constant are also analyzed.
