摘　　要：本文报道了Ln(DBM)_3·H_2O的简正坐标分析结果,计算中采用了单螯合坏近似模型,计算结果和红外、拉曼光谱观测频率符合较好,所得到的一组力常数,具有较好的转移性质.讨论了一些重要谱带的性质。In this paper, FT-IR and Raman spectra of Lanthanide-Dibenzoylmethanate chel-ate compounds were reported. A normal coordinate treatment was made by using asingle chelate ring model. The calulated frequencies were in good agreement withthe observed ones. The force constants obtained from the calculation have a goodtransferable property. Some important bands were discussed in detail.s
