摘要
制备了稀土离子Ln_(3+)(Ln=La,Ce,Pr,Nd,Sm,Eu,Gd,Tb,Dy)与1-羟基蒽酿的络合物,测定了它们和氘代1-羟基蒽醌在4000~50cm^(-1)范围内的红外光谱,对观察红外吸收带进行分析和归属.发现了某些对金属离子敏感的谱带,确定了配位键的伸缩振动.
Infrared spectra of 1-Hydroxyanthraquinone and rare earth elements (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb and Dy) complexes in the range between 4000-50 cm-1 were determined on Bruker 113 V Fourier transform spectrometer. The bands, including the new bands measured in the far infrared region, have been assigned by isotropic substitution technique and spectral change after forming complexes. The characterization of coordination bond was elucidated.
