BANGO SEA XLOC/HMBC-H2OBC: complete heteronuclear correlation within minutes from one NMR pulse sequence.

Novel NMR experiments, BANGO SEA XLOC-H2OBC or BANGO HMBC-H2OBC, can deliver complete heteronuclear correlation maps on a time scale of minutes for small molecules. By way of example, it is demonstrated that all intra- and inter-residue H-1 and C-13 correlations and assignments of a trisaccharide are obtained in 20 or 5 minutes of instrument time without or with 25% NUS, respectively.
