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
Artifacts in the form of cross peaks have been observed along two-and three-quantum diagonals in single-quantum two-dimensional correlated (COW) spectra of several peptides and oligonucleotides. These have been identified as due to the presence of a non-equilibrium state of kind I (a state describab
