Summary Several pseudo-3D NMR experiments are proposed for removal of overlaps in 1D 1H NMR spectra. A selective pulse and a chemical-shift-selective filter are used for double selection of the magnetization during the course of the pulse sequence. Different polarization transfer mechanisms are combined into pseudo-3D COSY-RELAY, COSY-TOCSY, COSY-NOESY, COSY-ROESY, RELAY-NOESY, RELAY-ROESY, RELAY-RELAY and RELAY-TOCSY experiments. The techniques are illustrated on oligo- and polysaccharide samples.
