| 摘 要： | 用二维拉曼相关光谱技术研究了稀土离子Eu^3 对血红蛋白结构的影响。结果表明，以Eu^3 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Eu^3 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 Eu 3+ on hemoglobin(Hb) was studied by using two dimensional Raman correlation spectroscopy. The results show that with the variation of Eu 3+ concentrations as perturbation, the oxidation state of Hb and its spin state are both sensitive to the perturbation. Eu 3+ added to Hb affects the oxidation and spin state synchronously. The four structure sensitive bands of Hb are more accessible to the Eu 3+ than other bands. |
