摘要： 用二维拉曼相关光谱技术研究了稀土离子Eu3+对血红蛋白结构的影响.结果表明,以Eu3+浓度作为微扰,血红蛋白的结构敏感谱带均对微扰敏感,氧化态和自旋态标志谱带1374和1640cm-1发生了同步变化,且明显先于其它谱带强度的变化,稀土离子Eu3+对血红蛋白的作用主要是影响它的氧化态和自旋态.

Abstract: The effect of rare earth ion Eu3+ on hemoglobin(Hb) was studied by using two dimensional Raman correlation spectroscopy. The results show that with the variation of Eu3+ concentrations as perturbation, the oxidation state of Hb and its spin state are both sensitive to the perturbation. Eu3+ added to Hb affects the oxidation and spin state synchronously. The four structure sensitive bands of Hb are more accessible to the Eu3+ than other bands.

Key words: Rare earth ion, Hemoglobin, Oxidation state, Spin state, 2D Raman correlation spectroscopy
