## Abstract We describe here new versions of the DEPT phase‐encoded HMQC experiment that offer robust performance and improved sensitivity. The new sequences rely on frequency‐swept proton and carbon pulses to minimize signal losses from miscalibrated pulses while providing ‘J compensation’ to opti

✦ Synopsis
Abstract
Two new pulse sequences are presented for the acquisition of DEPT–HMQC spectra, based on the original experiment of Kessler et al. The new sequences employ modifications intended to make the experiment well suited for high‐throughput acquisition and automated analysis. The sequences use coherence selection with gradients to reduce artifacts and constant‐time evolution to suppress unwanted F~1~ modulation. In addition, the new sequences require fewer pulses than the original experiment, and perform well even when pulse lengths are slightly mis‐set. Copyright © 2001 John Wiley & Sons, Ltd.

## Abstract This article describes new versions of the DEPT phase‐edited heteronuclear single quantum correlation (HSQC) pulse sequence with sensitivity enhancement. The sequences incorporate frequency‐swept carbon and proton pulses. The new experiments are inherently robust, well‐suited for a high
