| 摘 要： | 本文通过对近红外激发傅里叶变换拉曼光谱（ＮＩＲ－ＦＴ－Ｒａｍａｎ）与表面增强拉曼散射（Ｓｕｒｆａｃｅ Ｅｎｈａｎｃｅｄ Ｒａｍａｎ Ｓｃａｔｔｅｒｉｎｇ，ＳＥＲＳ）技术的联用，没得胆红素及其络合物Ｎａ２ＢＲ，ＣａＢＲ与ＣｕＢＲ在银溶胶中的ＳＥＲＳ光谱。结果表明，这一类与胆结石密切相关的生物分子络合物具有不同的配位方式，且在银胶表面采取不同的吸附取向，并从配位化学角度初步解释了黑色结石的黑色成因。

| Abstract: | SERS spectra of bilirubin and its complexes were determined in Ag sol by the technique of the connection between NIR-FT-Raman and SERS. The spectra showed that this kind of biological complexes, which is closely related to gallstones, differ in coordination pattens and adsorptive orientation as well. The reason why the black-pigment gallstone exhibits that peculiar dark color was also given from the coordination-chemistry point of view. |
