A new and promising method for recording phase-sensitive HMQC and HMQC-TOCSY spectra of molecules with natural-abundance carbon-13 isotopes is described. It avoids phase modulation of the NMR signals obtained with conventional coherence-transfer pathway selection using pulsed field gradients and results in an improvement in sensitivity. The spectra can be processed according to standard States–Haberkorn–Ruben methods, making the incorporation of gradients transparent to routine users. Strong unwanted proton signals from the carbon-12 isotopomers are attenuated by a double-gradient BIRD pulse at the beginning of the pulse sequences, resulting in high-quality spectra. By incorporating carefully designed purging sequences, high-resolution proton multiplets are obtained.
