INFLUENCE OF KCl ON THE ORIENTATION OF ADSORBED MOLECULE IN SERS SYSTEM
KCl对表面增强喇曼光谱系统中分子吸附取向的影响

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.
