Ultra-high dispersion NMR reveals new levels of detail

Pure shift NMR techniques can provide exquisite resolution, enabling chemists to analyse samples that would otherwise require unrealistically high magnetic fields. Although powerful, such techniques remain little used, in part because of the false perception that they are unsuitable for daily use. The present paper shows that this need not be the case and that high quality results can be produced routinely even for dilute and highly complex samples.
