Examples of 2D spectra recorded in a single scan, shown together with the corresponding NMR pulse sequence. (a) Ultrafast constant-time J-resolved spectrum recorded in 500 ms at 500 MHz on a cinnamic acid sample in DMSO-d6 (54). (b) Ultrafast constant-time COSY spectrum recorded in 100 ms at 500 MHz with a cryoprobe on a mixture of 6 metabolites (Alanine, Threonine, Glutamic acid, Valine, Serine, Myo-Inositol) in D2O. (c) Ultrafast real-time TOCSY spectrum recorded in 150 ms at 500 MHz on a n-butylchloride sample in CDCl3 (56). (d) Ultrafast real-time 1H-15N HSQC spectrum recorded in two scans at 800 MHz with a cryoprobe on a lyophilized protein A sample in D2O (46). (e) Ultrafast constant-time 1H-13C HSQC spectrum recorded in a single scan following the injection of hyperpolarized vitamin E at a 12 mM concentration (56).
