摘要
本文从观察光的吸收谱变化觉察到分子吸附在银胶、银镜上所出现的电荷转移跃迁;同时测量了电荷转移对吸附分子喇曼信号的增强.并且对其机理进行了初步分析.
The band of charge transfer transition is detected in optical absorption spectra when molecules are adsorbed on silver surface in silver sol and silver mirror. The charge transfer enhano ement for Kaman signal in Ag-molecule system is measured and its mechanism is analysed at the same time.
