摘　　要：稀土β-二酮络合物被用作激光材料和核磁位移试剂已进行了广泛的研究。根据红外光谱峰值、强度和力常数可讨论配位键性质。对某些(TTA)3M类型稀土螯合物的红外光谱虽已见报导,但对四个双齿配位体与稀土元素螯合成络合物的红外光谱却研究甚少。The infrared absorption spectra of thenoyltrifluoroacetonates of rare earth of (TTA)4ML (M = La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er,Tm, Yb and Lu;L=Lewis base) have been mearsured from 4000cm^(-1) to 700cm^(-1). The assignments of the observed main bands to different vibrational modes are carried out. In the 4000-700cm^(-1) region, the spectra are almost independent of the rare earth ion.
