DEPT‐related sequences for selective long‐range heteronuclear chemical shift correlation spectroscopy

Katalin E. Kövér, Gy. Batta

Abstract

Abstract DEPT‐related sequences are proposed which suppress the generally unnecessary direct proton‐carbon correlations from the long‐range optimized heteronuclear chemical shift correlation spectra. One‐bond modulation of long‐range response intensities is removed through the use of a BIRD pulse train. It is demonstrated that these modified sequences are superior to the original 2D DEPT experiment for the detection of long‐range connectivities of protonated carbons.
