Orientation of 1- and 2-methylimidazole on silver electrodes determined with surface-enhanced Raman scattering

Article Abstract:

A study was conducted to analyze the potential-dependent orientation of 1 and 2-methylimidazole on silver electrodes using surface-enhanced Raman scattering. Conventional metallographic procedures were utilized to prepare the silver electrodes for cyclic voltammetry and differential capacitance measurements. 2-MeIm was then purified by recrystallization from benzene.In addition, a Coherent Radiation 5999 tunable dye laser was used to carry out laser excitation at 600 nm.

Surface-enhanced Raman scattering based vibrational stark effect as a spatial probe of interfacial electric fields in the diffuse double layer

Article Abstract:

In-situ surface-enhanced Raman scattering (SERS)-based spectroelectrochemical method is used for investigation of spatial structure of the diffuse double layer at a self-assembled monolayer (SAM)/ aqueous solution interface. The results demonstrate the ability of this spectroelectrochemical experiment to characterize diffuse double-layer structure at electrochemical interfaces on a subnanometer distance scale.
