Shell-isolated nanoparticle-enhanced Raman spectroscopy of thiocyanate on smooth gold electrodes

金电极-硫氰酸盐体系的红外及拉曼光谱研究在近几十年的时间里已被大量开展，然而针对其光谱数据的分析却存在大量分歧，特别是C-N伸缩振动模频率的电势依赖关系。这些问题的存在导致了硫氰酸盐在金表面吸附构型的争议，因而促使了我们对该体系做进一步的研究。利用壳层隔绝纳米粒子增强拉曼光谱(SHINERS)及表面增强拉曼光谱(SERS)相互对照，我们揭示了中性溶液中硫氰酸根离子(SCN-)在结构明确的Au(111)单晶表面的吸附行为。研究发现，频率位于2080cm-1附近以N端吸附形式存在的SCN-其C-N伸缩振动模(νC-N)可在整个电势窗口内被观察到；在拉曼谱图中首先以S端吸附的SCN-νC-N肩峰形式...The system gold electrode‐thiocyanate has been extensively studied for decades by infrared and Raman spectroscopy. However, some discrepancy in the data (especially regarding to the potential dependence of the frequency of the band corresponding to the C‐N stretching mode) and, subsequently, with the adsorption configuration, makes necessary a further investigation of this system using well‐define...学位：博士后院系专业：化学化工学院_化学学号：201267005
