Abstract:Finally, thiocyanate (SCN) adsorption on Au electrode is examined. Both the calculations and the spectroscopy show that three different geometries are adopted by SCN in the potential region studied (0.0 V ≤ E ≤ 1.2 V vs. NHE). At low potential both N-bound and S-bound forms are found, at intermediate potentials around Epzc the S-bound form dominates, and at high potentials SCN associates with the surface via a bridging geometry. The different Stark slopes observed for the C-N stretch in the end-on and bridging forms are attributed to the lowest unoccupied molecular orbital (LUMO).
