硫脲吸附在电镀银表面的SERS

SERS of Thiourea Adsorbed on the Plated Silver Suface

研究了在盐酸水溶中硫脲分子的表面增强拉曼散射。实验结果表明：硫脲分子倾斜吸附在银表面。当盐酸浓度增加时，硫脲分子平面更加偏离银表面的法线方向。

We have studied the surface enhanced Raman scattering of thiourea adsorbed on plated silver surface in HCl aqueous solution. The results show that the thiourea molecules are inclined to adsorbed on the silver surface. When the concentration of HCl is increased,the molecular plane of the thioured deviates more from the normal line of the silver surface.
