Improving the resolution in proton-detected through-space heteronuclear multiple quantum correlation NMR spectroscopy

Resolution enhancement of the six one-bond cross-peaks in 1H-{13C} HMQC spectra of histidine at 9.4 T; with νR = 32.3 kHz, ν1,decrms = 123 (CWmedium), 175 (CWlarge), 123 (SAM3) and 113 kHz (SAM4).97
