| 摘 要： | 报道了植酸分子吸附在氧化银溶胶表面获得的表面增强拉曼散射(SERS)光谱。通过ab-initio/STO-3量子化学计算结果归属了植酸分子的振动模，并根据SERS光谱推测植酸分子是通过六个磷酸酯键中的四个与氧化银胶粒表面产生吸附作用。

| Abstract: | Surface enhanced Raman scattering spectra of phytic acid were recorded in the sol oxide silver. Based on ab-initio/ STO-3 quantum calculations results, assignments to the vibrational modes of phytic acid were carried out. On the basis of the mechanism of SERS, the adsorption modes were suggested that phytic acid chemically adsorbed on the oxide silver surface through four phosphate bonds. |
