## Abstract Resolution enhancement in NMR spectra, acquired in spatially or temporally varying magnetic fields, can be achieved with 2D pulse sequences detecting intermolecular zeroβquantum coherences (iZQC). The insensitivity towards long range field distortions renders these methods particularly
New pulse sequences for two-dimensional phase-sensitive detection of heteronuclear zero- and double-quantum coherence are presented for use with and without pulsed field gradients. The magnetization is phase modulated during t1 and then transferred to a proton for detection using a novel approach si
