摘要
本文从实验上测量表面增强喇曼光谱(SERS)系统中掺入KCl后分子特征喇曼峰相对强度的变化,由此进一步分析分子在表面上吸附取向的变化。
The variation of surface enhanced Raman scattering was observed as a small amount of KCl was added in SERS system and the intensity ratio of characteristic Raman peaks was detected for two kinds of molecules. In addition the change of orientation of adsorbed molecule on the silver surface was also analysed.
