✦ Synopsis

The performance of the 1H 2D PFG-DQ experiment is analysed with theory and with some practical examples. The use of di †erent angles for the detection pulse allows sensitivity optimization and spectral editing. Almost complete water suppression, high sensitivity, predominantly absorption lineshape, very low noise and t 1 absence of strong diagonal signals make the method very suitable for the analysis of complex mixtures, e.g. bio-Ñuids, cell cultures, natural product extracts and combinatorial chemistry samples. The method is also compared with the well known TOCSY and COSY experiments.

## Abstract The ^1^H CW off‐resonance decoupled ^13^C NMR spectra of pheromones and unsaturated fatty acids were measured for the determination of the configuration of double bonds of the type CH~2~CH  CHCH~2~. The decoupling frequency corresponded to the resonance frequency of the CH~2~ proto
