NMR (magnetic resonance) works on materials of odd number of protons. Copper with its atomic weight of 64 contains 29 protons and 35 neutrons. Would the technique work on 64Cu then? The extensions then goes, if NMR work on other metals as well.
Thanks!
You can perform NMR with every nucleus that has a nuclear spin. For copper this appears to be 63Cu and 65Cu:

The same is also true for other metals (colleague of mine performed vanadium NMR once and I also know that calcium works). On the other hand, many of these do not have favorable NMR properties so the spectra look ugly.
64Cu has a spin (parity) of 1+ and a magnetic moment of about -0.22 µN, resulting in a Larmor frequency of about (-)1.7 MHz/T. In general, NMR spectroscopy of metal nuclei is feasible; check e.g. Benn R, Rufińska A. High‐resolution metal NMR spectroscopy of organometallic compounds. .
Data about 64Cu is from:
- Nuclear spins, magnetic moments and quadrupole moments of Cu isotopes from N = 28 to N = 46: probes for core polarization effects polarization effects. arXiv:1011.5420. Phys.Rev.C82:064311,2010. DOI: 10.1103/PhysRevC.82.064311.

This discussion is old, but just to correct some errors (" odd number of protons "), look here: http://ebyte.it/stan/blog08b.html#08Oct15.
Btw, why to ask such questions, if typing "Copper NMR" into Google, hundreds of references come up? Like this one: https://www.pascal-man.com/periodic-table/copper.shtml.
We do not live in middle ages any more.
