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
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
