利用表面增强拉曼散射（Sers）技术研究了1，2，3-三氮唑在银和金胶体纳米粒子上的吸附。通过记录Ag（I）/1，2，3-三唑配合物的正常拉曼光谱，获得了关于银吸附机理的进一步信息。Sers数据解释的帮助下，结合到银或金表面吸附原子的配体模型的密度泛函理论计算。1，2，3-三唑以其阴离子形式通过N-1和N-3原子的孤对与银和金基底相互作用，相对于金属表面具有倾斜取向。
The adsorption of 1,2,3-triazole on silver and gold colloidal nanoparticles is studied by means of surface enhanced Raman scattering (SERS). Further information about the adsorption mechanism on silver is obtained by recording the normal Raman spectra of the Ag(I)/1,2,3-triazole coordination compound. SERS data are interpreted with the help of density functional theoretical calculations of models of the ligand bound to silver or gold surface adatoms. 1,2,3-Triazole interacts with both silver and gold substrates in its anionic form through the lone pairs of the N-1 and N-3 atoms with a tilted orientation with respect to the metal surface.
