Measuring nitrogen quadrupolar coupling with ~13C detected wide-line ~14N NMR under magic-angle spinning

摘要

A ~(13)C-detected ~(14)N wide-line NMR experiment is described for measuring nitrogen quadrupolar coupling under magic-angle spinning. Nitrogen is one of the most important elements in nearly all branches of chemistry. While ~(15)N NMR has been widely used with the favorable NMR properties of a spin-1/2, the highly abundant ~(14)N has been rarely studied.
