Abstract

A new pulse sequence is proposed for the determination of scalar coupling correlation in small‐ and medium‐sized organic compounds. The method uses a combination of the double pulsed field gradient spin‐echo (DPFGSE) and the selective population transfer (SPT) techniques and is shown to be useful in the analysis of complex spectra with many overlapped signals. The usefulness of this method in the structural elucidation of natural substances is demonstrated using strychnine and digitoxin as examples. Copyright © 2004 John Wiley & Sons, Ltd.
