Ultrafast 2D COSY with constant-time phase-modulated spatial encoding.
TLDR
Comparisons between the experimental results and those of the previous real-time phase-modulated spatial encoding method demonstrate that the signal-to-noise ratio and resolution of the 2D COSY spectra are improved, and a good 2DCOSY spectrum is easier to achieve by using the proposed methods.About:

Ultrafast 2D NMR: An Emerging Tool in Analytical Spectroscopy
Patrick Giraudeau,Lucio Frydman +1 more
TL;DR: This review summarizes the principles and main developments that have contributed to the success of the so-called ultrafast (UF) 2D NMR methodology and focuses on applications that have been recently demonstrated in various areas of analytical chemistry.
Journal ArticleDOI
Spatial encoding and spatial selection methods in high-resolution NMR spectroscopy.
TL;DR: This review article provides a description of several spatial encoding and spatial selection methods, including single-scan multidimensional experiments (ultrafast 2D NMR, DOSY, Z spectroscopy, inversion recovery and Laplace NMR), pure shift and selective refocusing experiments, including Zangger-Sterk decoupling, G-SERF and PSYCHE, a Z filter, and fast-pulsing slice-selective experiments.

A new gradient-controlled method for improving the spectral width of ultrafast 2D NMR experiments.
Patrick Giraudeau,Serge Akoka +1 more
TL;DR: A gradient-controlled folding method that leads to "folded-like" spectra along the ultrafast dimension without degrading the resolution, and appears to be particularly promising for heteronuclear 2D NMR.

Sensitivity and lineshape improvement in ultrafast 2D NMR by optimized apodization in the spatially encoded dimension
Patrick Giraudeau,Serge Akoka +1 more
TL;DR: This work identifies the origin of distortions in lineshapes characterized by asymmetric sinc wiggles by means of numerical simulations compared with experimental data and proposes a processing approach to improve lineshape while increasing the sensitivity of ultrafast experiments.
Journal ArticleDOI
Spatially encoded ultrafast high-resolution 2D homonuclear correlation spectroscopy in inhomogeneous fields
TL;DR: Two new pulse sequences tracking the differences of the precession frequencies of two coupled spins are proposed to ultrafast achieve high-resolution 2D correlation spectroscopy (COSY and TOCSY) in inhomogeneous fields in a single scan.

Two‐dimensional spectroscopy. Application to nuclear magnetic resonance
TL;DR: In this article, the possibilities for the extension of spectroscopy to two dimensions are discussed, including the elucidation of energy level diagrams, the observation of multiple quantum transitions, and the recording of high-resolution spectra in inhomogenous magnetic fields.
Journal ArticleDOI
Improved spectral resolution in cosy 1H NMR spectra of proteins via double quantum filtering.
TL;DR: The elimination of the dispersive character of the diagonal peaks in phase-sensitive, double quantum-filtered COSY spectra allows identification of cross peaks lying immediately adjacent to the diagonal, which represents a significant improvement over the conventional COSy experiment.

Very fast two-dimensional NMR spectroscopy for real-time investigation of dynamic events in proteins on the time scale of seconds.
Paul Schanda,Bernhard Brutscher +1 more
TL;DR: It is demonstrated for different protein samples that 2D 1H-15N correlation NMR spectra can be recorded in a few seconds of acquisition time using a new band-selective optimized flip-angle short-transient heteronuclear multiple quantum coherence experiment.

The acquisition of multidimensional NMR spectra within a single scan
TL;DR: A scheme enabling the complete sampling of multidimensional NMR domains within a single continuous acquisition is introduced and exemplified, which could enable the characterization of transient events such as proteins folding, 2D NMR experiments on samples being chromatographed, and the incorporation of spectroscopic 2D sequences into in vivo imaging investigations.
