A spin-echo sequence is proposed for the suppression of the generally unnecessary strong direct cross-peaks in two-dimensional heteronuclear NOE and relayed incoherent transfer spectroscopy. The procedure also increases the intensity of 'remote peaks,' thereby enhancing the sensitivity of these tech

β¦ Synopsis
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 more easily.

A novel method for suppression of diagonal peaks in the amide region of NOESY NMR spectra of 15 N-labeled proteins is presented. The method is particularly useful for larger proteins at high magnetic fields where interference between dipolar and chemical shift anisotropy relaxation mechanisms result
## Abstract Several 1D and 2D inverse proton editing pulse sequences have recently been introduced. One of these, the REPAY sequence, allows the individual editing of XH or XH~2~ groups. Some new 2D combinations of oneβ and twoβdimensional REPAY experiments with a COSY or TOCSY transfer are describ
