Figure 5: Raman spectroelectrochemistry of FcMeOH at graphene electrode device 1.
From: In-situ Raman spectroscopy to elucidate the influence of adsorption in graphene electrochemistry

The voltammogram (a) shows three performed FcMeOH measurements and the control curve of the background electrolyte (black). The G-peak position extracted from the in-situ recorded Raman spectrum vs the applied potential (b) shows curves different from the control (black), indicating adsorption.
