Some of the Other Nuclei

In general, for solution studies, copper NMR seems to be of use primarily as a supporting technique. This is less true for the case of solid-state samples, where both Cu(I) and Cu(II) species can be observed, in conjunction with measurements of Knight shifts, copper NQR and/or NMR/NQR spectroscopy of some of the other nuclei present in the system. The vast majority of copper NMR reports over the last five years have dealt with solid-state studies of copper materials, especially those materials recognized as superconductors.
