NMR spectra of 14N (spin I=1) are obtained by indirect detection in powders spinning at the magic angle. The method relies on the transfer of coherence from a neighboring “spy” nucleus with S=1/2, such as 13C or 1H, to single‐ or double‐quantum transitions of 14N nuclei. The transfer of coherence ca...
