2D spectra, particularly for homonuclear correlation, can show a variety of artifactual signals in the F 1 domain. Common sources include carry-over of signal modulation from one transient to the next ("rapid pulsing artifacts") and systematic variations in room temperature ("parallel diagonals"). I

A simple and efficient technique, called phase-shift presaturation, for solvent suppression in one-and two-dimensional NMR experiments is proposed and tested. The solvent signal can he considerably suppressed when the traditional presaturation technique is modified by a a/2 shift of the rfphase duri
Pure absorption phase-sensitive shift-correlated 'H NMR spectra were shown to furnish complete information on chemical shifts, their connectivities (including one-and two-step remote connectivities) and coupling constants for oligosaccharides of considerable complexity. Therefore, a strategy using t
