| 摘 要： | 本文在电镀沉积的银衬底上，研究了硫脲分子在酸性溶液中的表面增强拉曼散射。结果表明，硫脲分子是通过硫原子倾斜着吸附在银表面；当溶液中的ＨＣｌ浓度增加时，在银表面吸附的硫脲分子面更加偏离银表面的法线方向；实验结果还暗示，该体系存在着较强的化学增强机制。

| Abstract: | Surface enhanced Raman scattering of thiourea adsorbed on the plated silver surface in an acidic solution has been studied.The results show that the thiourea molecules are inclined to adsorbed on the silver surface via sulphur.When the concentration of HCl in the solution is increased,the plane of the thiourea molecule deviates more from the normal line of the silver surface.The experimental results also suggest that the rather strong chemical enhanced mechanism would exist in this system. |
