(a) The NMR spectrum for a small molecule ligand will depict a narrow linewidth due to a longer transverse relaxation time. (b) In contrast, a protein has a shorter transverse relaxation time and thus a broad linewidth is shown. (c) TROSY prolongs the transverse relaxation times and thereby improves the protein signal in the spectrum.
