Real‐time band‐selective homonuclear 1 H decoupling during data acquisition of z‐filtered J ‐resolved spectroscopy produces 1 H‐decoupled 1 H NMR spectra and leads to sensitivity enhancement and improved resolution, and thus aids the measurement of J couplings and residual dipolar couplings in crowded regions of 1 H NMR spectrum. High quality spectra from peptides, organic molecules, and also from enantiomers dissolved in weakly aligned chiral media are reported.
