|a The speed of multidimensional NMR spectroscopy can be significantly increased by drastically shortening the customary relaxation delay between scans. The consequent loss of longitudinal magnetization can be retrieved if 'new' polarization is transferred from nearby spins. For correlation spectroscopy involving heteronuclei (X=13C or 15N), protons not directly bound to X can repeatedly transfer polarization to the directly bound protons through Hartmann-Hahn mixing. An order of magnitude increase in speed has been observed for the 600 MHz two-dimensional HMQC spectra of amikacin and strychnine using this technique, and it also reduces the noisy F1 ridges that degrade many heteronuclear correlation spectra recorded with short recovery times
