Sum frequency generation (SFG) spectroscopy using internal reflection geometry was employed to investigate the conformational order of octadecanethiol (ODT) monolayer on gold thin films in an electrolyte solution. This approach is convinced to be useful to study the molecular structure on the electrode/solution interface under electrochemical condition. 表面和頻光譜分析系統(tǒng)(SFG) PL2230系列高能量全固態(tài)鎖模皮秒Nd:YAG激光器 Ekspla CARS 相干反斯托克斯拉曼顯微光譜儀
