Raman spectra of solid complexes RE(His)(NO3)3 x H2O (RE = La-Nd, Sm-Lu, Y; His = L-alpha-histidine ) have been investigated. The results indicate that RE3+ coordinates with one O atome of carboxyl group in the complex, while amino group and imidazole ring do not take part in coordination and NO3 is double coordination. The vibration peaks of carboxyl group delta(v)COO-(as-s) were plotted against the atomic number of the lanthanoids, which obeys Oddo-Harkins law.
对固体配合物RE(His)(NO₃)₃·xH₂O（RE = La - Nd，Sm - Lu，Y；His = L-α-组氨酸）的拉曼光谱进行了研究。结果表明，在该配合物中RE³⁺与羧基的一个氧原子配位，而氨基和咪唑环不参与配位，且NO₃为双配位。将羧基δ(v)COO⁻(as - s)的振动峰相对于镧系元素的原子序数作图，其符合奥多-哈金斯定律。
