1,4‐dibromobenzene (DBB) was adsorbed on a polycrystalline gold electrode from aqueous solutions. In situ vibrational infrared (IR) and Raman spectroscopy yielded results implying an edge‐on coordination of the adsorbed molecule. Adsorption does not only involve the ring an system of the molecule, but also its bromide substituents. In comparison to the potential‐modulated in situ IR method, the Raman spectroscopy shows higher sensitivity for adsorbate detection.
