## Abstract The incorporation of pulsedβfield gradients for coherence selection into 1D protonβdetected pulse sequences provides clean spectra free of cancellation artifacts but, frequently, at the expense of a sensitivity loss by a theoretical factor of 2 due to the rejection of another contribute

The selection of well-defined coherence transfer pathways is an essential feature of all but the simplest NMR and EPR pulse sequences. This selection can be achieved by phase cycling and by pulsed field gradients. The properties of the RF-pulses (flip angle, offset effects, inhomogeneity) and transp
Modifications of the HSQC and HMBC pulse sequences and their application to the study of the antibiotic nosiheptide are reported. Reduction of t,-noise in the 'H-I5N HSQC experiment is achieved by the combination of a BIRD-relaxation preparation period and introduction of a purging spin-locking puls
