Real-Time Chemical-Shift Scaling in High-Resolution NMR Spectroscopy

Imitating a low-field spectrometer may seem a strange concept, but might be of great help to laboratories that no longer have access to such machines. For example, slowing down the average evolution of the chemical shift during NMR-signal acquisition changes the strength of coupling between spins and the effects of chemical exchange. The spectra of quinine shown were obtained with the NMR technique proposed here.
