“…In situ vibrational spectroscopies were also used to investigate these reactions. ,,,,− Surface-enhanced Raman spectroscopy has shown that TU adsorbs strongly on the metal surface via the sulfur atom in a wide potential range and desorbs at sufficiently negative potentials. ,,,− On the other hand, the combination of Fourier transform infrared spectroscopy (FTIRS) with electrochemical techniques enables the acquisition of molecular information concerning the direct interaction of the adsorbate at the metal/electrolyte interface. , Consequently, in situ FTIRS appears also to be a useful technique to study the interaction of organic plating additives.…”
