摘要： 以三电极电池系统在不同电位下的在位测量测得四磺基苯基卟啉钠水溶液(浓度为5×10-5mol/L)的表面增强拉曼谱.结果表明,在接近第一还原态电位处对吸附分子活化后,可得到较大倍数的增强信号(107数量级)、对照简正坐标计算结果,发现与N原子有关的振动模式有较大的增强,在此基础上提出了增强机理.

Abstract: In this paper, we observe the Surface Enhance Raman Scattering of TPPS4 adsorbed on Ag electrode by activation at potential 1.2 Vwhich is close to the reduction potential of TPPS.The spectral peaks were assigned and a normal coordinate analysis was performed for modes in plane by using SGVFFfield.The results show that the vibrational modes which are relative to Natom were enhanced much areatly.In contrast to these results we explain the mechanism of TPPS4 enhanced effect.
