[2] Deuterium NMR has a range of chemical shift similar to proton NMR but with poor resolution, due to the smaller magnitude of the magnetic dipole moment of the deuteron relative to the proton.
2H NMR spectra are especially informative in the solid state because of its relatively small quadrupole moment in comparison with those of bigger quadrupolar nuclei such as chlorine-35.
This allows for the whole spectrum to be excited with practically achievable pulses of a few microseconds in duration.
[2] Thus, 2H NMR can probe orientation distributions in partially ordered deuterated polymers.
[2] Changes in C-D bond orientation due to molecular motions have pronounced effects on the spectral line shape.
