Abstract Two-dimensional (2D) homonuclear correlated spectra manifest connectivities
between spin-coupled nuclei and can thus provide assignments of individual spin systems
in complex 1 H NMR spectra. Two experimental techniques discussed in this paper, spin-
echo correlated spectroscopy and foldover-corrected correlated spectroscopy, are
particularly suitable versions for handling the large data matrices encountered in work with
biological macromolecules. This paper explains the fundamental aspects of these two …
