Abstract

A pulsed field gradient version of the sensitivity-enhanced 2D TOCSY experiment is proposed which yields high-quality spectra with improved sensitivity and a minimum of two scans per t1 increment. For rapid acquisition of ID TOCSY spectra, the 1D DPFGSE-TOCSY experiment was modified to include phase-encoded multiple-selective excitation followed by a simple spectral editing. Combination of these two building blocks is used in a sensitivity-enhanced 2D analog of the 3D TOCSY-TOCSY experiment which provides an efficient tool for resolving severely overlapped signals of oligomers in short experimental time.
