Default Ultrafast 2D NMR spectroscopy using a continuous spatial encoding of the spin interac

Ultrafast 2D NMR spectroscopy using a continuous spatial encoding of the spin interactions.

Related Articles Ultrafast 2D NMR spectroscopy using a continuous spatial encoding of the spin interactions.

J Magn Reson. 2004 Nov;171(1):163-70

Authors: Shrot Y, Shapira B, Frydman L

A new protocol for acquiring multidimensional NMR spectra within a single scan is introduced and illustrated. The approach relies on applying a pair of frequency-chirped excitation and storage pulses in combination with echoing magnetic field gradients, in order to impart the kind of linear spatial encoding of the NMR interactions that is required by ultrafast 2D NMR spectroscopy. It is found that when dealing with 2D NMR experiments involving a t1 amplitude-modulation of the spin evolution, such continuous encoding scheme presents a number of advantages over alternatives employing discrete excitation pulses. From an experimental standpoint this is mainly reflected by the use of a single pair of bipolar gradients during the course of the indirect-domain encoding, as opposed to the numerous (and more intense) gradient echoes required so far. In terms of the spectral outcome, main advantages of the continuous spatial encoding scheme are the avoidance of "ghost peaks" and of "enveloping effects" associated to the discrete excitation mode. The principles underlying this new spatial encoding protocol are derived, and its applicability is demonstrated with homo- and heteronuclear 2D ultrafast NMR applications on small molecule and on protein samples.

Signal enhancement for the sensitivity-limited solid state NMR experiments using a continuous, non-uniform acquisition scheme. J Magn Reson. 2011 Aug 30; Authors: Qiang W Abstract We describe a sampling scheme for the two-dimensional (2D) solid state NMR experiments, which can be readily applied to the sensitivity-limited samples. The sampling scheme utilizes continuous, non-uniform sampling profile for the...

MathNMR: Mathematica package for spin and spatial tensor manipulations http://www.nyu.edu/projects/jerschow/graphical_commutator.png Spin and spatial tensor manipulations are frequently required to describe and the theory of NMR experiments. This is a Mathematica package, which provides some of the most common functions for these calculations. Examples are the calculation of matrix representations of operators, commutators, projections, rotations, Redfield matrix elements, matrix decomposition into basis operators, change of basis, coherence filtering, and the manipulation of...
