Distinguishing between two- and three-bond correlations for all 13C multiplicities in heteronuclear NMR spectroscopy†
Abstract
A novel two-dimensional method, SEA XLOC, for distinguishing between two- and three-bond correlations in heteronuclear NMR spectroscopy is introduced and demonstrated on ibuprofen and by a complete set of correlations with a simple and most complex quaternary 13C multiplet in strychnine.
