Abstract

We propose and demonstrate a 1D pulse sequence to convert double quantum coherence (DQC) of y phase with optimal efficiency, relying on single transition selection. Our sequence has a larger high‐sensitivity bandwidth with respect to the coupling, compared to other reconversion strategies. A modified version of the new pulse sequence provides the missing chemical shift and coupling information, at minor cost in sensitivity. Application to 1D ^13^C INADEQUATE is demonstrated.

Our new sequence is also applied to quadrupole coupled spin‐1 systems, such as ^2^H in lyotropic phase. Performance of the sequence may be fine‐tuned by pulse flip angle optimization, taking into account relaxation effects. Copyright © 2006 John Wiley & Sons, Ltd.

The possibility of exciting and detecting proton NMR double-quantum coherences in inhomogeneous static and radiofrequency magnetic fields was investigated. For this purpose specialized pulse sequences which partially refocus the strongly inhomogeneous evolution of the spin system and generate double

In this study we address the question of quantification of muscle lactate using double quantum filtered (DQF) 1 H NMR spectroscopy where dipolar and scalar coupled spectra are acquired. For this, lactate content in muscle samples was independently determined using a conventional enzymatic assay and
