A pulse sequence is presented to record diagonal-peak-free NOESY spectra. The technique is based on the principle that those peaks which do not undergo chemical shift changes (via NOE) during the mixing time are suppressed. This is achieved by two jump-return units before and after the mixing time.
Two-dimensional relayed-NOESY spectra are of utility in assigning connectivities in crowded spectra. A modified version OI this pulse sequence is described which removes uniforrnative diagonal peaks and one other type of unwanted peak. The resulting spectra are less crowded and can be. interpreted m
