Line shape considerations in ultrafast 2D NMR
Journal of Magnetic Resonance, 2004We have recently proposed and demonstrated an approach that enables the acquisition of 2D nuclear magnetic resonance (NMR) spectra within a single scan. The approach is based on spatially encoding the spins' evolution along the indirect domain with the aid of a magnetic field gradient, and subsequently decoding this information numerous times over the ...

Urinary Metabolite Quantification Employing 2D NMR Spectroscopy
Analytical Chemistry, 2008Two-dimensional (2D) nuclear magnetic resonance (NMR) spectroscopy is a fairly novel method for the quantification of metabolites in biological fluids and tissue extracts. We show in this contribution that, compared to 1D 1H spectra, superior quantification of human urinary metabolites is obtained from 2D 1H-13C heteronuclear single-quantum correlation

Progress in Hyperpolarized Ultrafast 2D NMR Spectroscopy
ChemPhysChem, 2008AbstractAn important development in the field of NMR spectroscopy has been the advent of hyperpolarization approaches, capable of yielding nuclear spin states whose value exceeds by orders‐of‐magnitude what even the highest‐field spectrometers can afford under Boltzmann equilibrium.

The Analyst, 2011
Quantitative Ultrafast (UF) 2D NMR is a very promising methodology enabling the acquisition of 2D spectra in a single scan. The analytical performances of UF 2D NMR have been highly increased in the last few years, however little is known about the sensitivity of ultrafast experiments versus conventional 2D NMR.

Elucidation of Lignin Structure by Quantitative 2D NMR
Chemistry – A European Journal, 2011AbstractQuick quantitative HSQC (QQ‐HSQC) was applied to quantitative evaluation of different inter‐unit linkages in an array of milled softwood and hardwood and technical lignins by using the guaiacyl C2 and syringyl C2–C6 signals as internal standards.

Fast hybrid multi‐dimensional NMR methods based on ultrafast 2D NMR
Magnetic Resonance in Chemistry, 2015Conventional multi‐dimensional (nD) NMR experiments are characterized by inherent long acquisition durations, while ultrafast (UF) NMR makes it possible to reduce to a few hundreds of milliseconds the overall acquisition duration of a complete nD NMR dataset.

We introduce a new class of NMR methods that exploit H-1 transverse nuclear spin noise for indirect detection in spectroscopy and imaging. We also report the first observations of C-13 and F-19 noise NMR spectra.

Ultrafast 2D NMR: Methods and Applications
2018International audience ; Multidimensional NMR (nD NMR) has become one of the most powerful spectroscopic tools to deliver diverse structural and functional insights into organic and biomolecules as well as on raw materials. A long-standing concern of nD NMR is related to its long experiment duration, arising from the need to sample the indirect ...

Applications of 2D NMR Spectroscopy to Carbohydrates
1990Two-dimensional high resolution nuclear magnetic resonance spectroscopy (2D NMR) is a powerful tool for determining the structure and conformation of carbohydrates in solution. Applications to carbohydrate problems have followed closely on the heels of development of sophisticated two dimensional — and now three dimensional — pulse sequences (Hoffman ...

2D WIN-NMR: BRUKER's PC-based display and processing package for 2D NMR data matrices
Fresenius' Journal of Analytical Chemistry, 1992Off-line retrieval and processing of data is a considerable advantage of a computer used separately from the spectrometer. 2D WIN-NMR — BRUKER's PC based display and processing package for 2D NMR data matrices — has been designed to fulfill two particular criteria: a variety of different display options allow an interactive interpretation of the 2D ...
