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.

Quantitative 2D liquid‐state NMR
Magnetic Resonance in Chemistry, 2014Two‐dimensional (2D) liquid‐state NMR has a very high potential to simultaneously determine the absolute concentration of small molecules in complex mixtures, thanks to its capacity to separate overlapping resonances. However, it suffers from two main drawbacks that probably explain its relatively late development.

2023
This chapter will describe various approaches to fast 2D NMR data acquisition through the use of multi-FID detection schemes. These provide routes to time-efficient data collection often with improved sensitivity per unit time through the recording of multiple data sets within a single experiment. These include methods that employ detection of a single

Fast 2D NMR and Hyperpolarization
2023This chapter presents an overview of both the methodology and applications of fast two-dimensional (2D) NMR using nuclear spin hyperpolarization. Fast 2D NMR methods extend the information available from NMR experiments through spin correlations while allowing the utilization of large signals from hyperpolarized spins for the study of fast processes ...
