摘要
报道了偶氮苯分子的常规拉曼谱(NRS)及其在活性衬底银胶上的表面增强拉曼散射(SERS)谱,对它的拉曼特征峰进行了指认。通过偶氮苯的常规拉曼光谱和SERS谱的对比表明,偶氮苯分子是通过苯环和近邻的氮原子吸附于金属表面,分子近于垂直站立在金属表面。
The normal Raman spectrum （NRS） and surface enhanced Raman scattering （SERS） of Azobenzene in silver sol are reported in this paper, Assignments of the Raman bands for Azobenzene molecules are presented. By the comparison of NRS and SERS of Azobenzene, it presents that Azobenzene molecules adsorbed on the metal surfaces through the phenyl and the adjacent N atom, Azobenzene molecules is vertical or a little tilted stand on the surface of silver sol.
