Abstract
We obtained C-13 and N-15 spectra and spin-lattice relaxation behaviors of electrochemically adsorbed CN- and CH3CN on a polycrystalline platinum electrode. T1T data provided information on the presence of conduction electrons on the adsorbates and on the adsorbate orientations. We show that adsorbed CN from cyanide media takes C-down with N-tilting to the surface with the tilt angle temperature dependent. In contrast, the adsorbed species from acetonitrile solutions has a side-on parallel orientation with the -CH3 group away from the surface. We also show that the NMR spectral sensitivity is adequate to observe nuclei with weaker signals, such as N-15.
