Seeking higher resolution and sensitivity for NMR of quadrupolar nuclei at ultrahigh magnetic fields.
We report the acquisition of solid-state NMR spectra of quadrupolar nuclei obtained at very high magnetic fields (25 and 40 T), thus improving spectral sensitivity and resolution. For an example compound, the MAS spectrum obtained at 40 T is nearly free from the second-order quadrupolar broadening and can be interpreted quantitatively in a very simple manner.
