As the concentration of KCl electrolyte increases, both the bending and stretching modes of the $H_2O$ were observed to increase in frequency.
In the case of Surface Enhanced Raman Scattering (SERS) of the $H_2O$, the Raman frequencies were observed to decrease as the applied voltage has the more negative value.
After the Oxidation-Reduction Cycle (ORC) of the SERS, the intensity of the $H_2O$ was observed to be sensitive to the applied voltage, especially in the intensity of continuum background.
During the ORC, the intensity of Raman Scaterring was observed to have the shape of the δ-function, which we attempted to correlate with the voltammogram dynamics.
