The results we have presented above show that quite high-sensitivity 13C and 15N NMR spectra of species adsorbed at a solid-liquid interface can now be obtained. The ability to prepare samples, record cyclic voltammograms, and obtain surface NMR spectra under potential control opens up new avenues for NMR at the solid-liquid interface in general, and at electrified interfaces in particular. The signal-to-noise ratios obtained at 8.45 enable initial studies of Tj and T2, and as we note below, will be greatly facilitated in the future via higher-field operation.
