Synchronized double rotation 2D NMR
Solid State Nuclear Magnetic Resonance, 2000Analytical expressions for multi-quantum signal generation of quadrupole nuclei have been derived. Combined with numerical simulation of the double rotor motion, a strategy is suggested for partial sideband suppression in multi-quantum NMR spectra. Synchronization of multi-quantum excitation and selective flip pulses with outer rotor motion increase ...

Some aspects of quantitative 2D NMR
Journal of Magnetic Resonance, 2005We have studied the application of 2D HSQC for quantitative measurements and propose some improvements to the previously published Q-HSQC method. Application of CPMG-INEPT for polarization transfer period suppresses the evolution of J(HH), and thus corrects the shape of the cross-peaks. The better cross-peak shape makes phase correction and integration

Single-scan 2D DOSY NMR spectroscopy
Journal of Magnetic Resonance, 2008Spatial encoding is a particular kind of spin manipulation that enables the acquisition of multidimensional NMR spectra within a single scan. This encoding has been shown to possess a general applicability and to enable the completion of arbitrary nD NMR acquisitions within a single transient.

While most fast 2D NMR strategies rely on short recycling delay or on the sparse sampling of the indirect dimension, ultrafast 2D NMR represents a change of paradigm by carrying out a spatial encoding of the resonance frequencies whereby spins located at different positions undergo distinct evolution periods within the same transient.

Single‐Scan 2D Hadamard NMR Spectroscopy
Angewandte Chemie International Edition, 2009AbstractScan and deliver: By combining imaging‐based spectral/spatial 2D radiofrequency manipulations (see scheme, left) with Hadamard‐weighting principles, 2D NMR spectra can be retrieved within a single scan (right). This approach can give homo‐ or heteronuclear correlations with an enhanced sensitivity over conventional ultrafast 2D NMR spectroscopy.

Micellar structure studied by 2D‐NMR
Recueil des Travaux Chimiques des Pays-Bas, 1988AbstractThis paper describes the possibility of using 2D‐NMR spectroscopy in the study of the morphology of micelles. In aqueous solution, the monomeric surfactant 1‐methyl‐4‐dodecylpyridinium iodide magnified image exhibits positive NOE's whereas negative NOE's are observed for the micellar aggregate.

Evaluation of Fast 2D NMR for Metabolomics
Analytical Chemistry, 2014Two-dimensional nuclear magnetic resonance (2D NMR) is increasingly explored as a tool for metabolomics because of its superior resolution compared to one-dimensional NMR (1D NMR). However, 2D NMR is characterized by longer acquisition times, which makes it less suitable for high-throughput studies.

NMR-based fluxomics: Quantitative 2D NMR methods for isotopomers analysis
Phytochemistry, 2007We have investigated the reliability of 2D-COSY and 2D-TOCSY experiments to provide accurate measurements of (13)C-enrichments in complex mixtures of (13)C-labelled metabolites. This was done from both theoretical considerations and experimental investigations.
