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.

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 ...

Pure Shift 2D NMR Spectroscopy
2023This chapter introduces pure shift NMR spectroscopy and shows how it can be combined with 2D methods to simplify spectra and aid interpretation. Typically, pure shift NMR is used to produce a spectrum that contains only chemical shift information in the 1H dimension, with signal overlap caused by wide multiplets removed or greatly reduced.

Multidimensional Fourier transform methods can simplify and manipulate magnetic resonance spectra, helping to determine the structures of large biomolecules. Researchers are also exploiting the shorter wavelengths of visible and infrared light to determine instantaneous molecular structures.

Written by active investigators in the field, this book describes state-of-the-art methods that can accelerate the acquisition of 2D NMR spectra in solution-state NMR. The acquisition of fast multi-dimensional NMR data has motivated numerous ground-breaking developments in NMR pulse sequences and associated data processing methods.

With the use of two-dimensional (2D) nuclear magnetic resonance (NMR) experiments (Aue et al., 1976; Bax, 1982), the potentialities of NMR for studies of biopolymers can be greatly enhanced. This paper describes 2D NMR experiments which are commonly used for work with proteins and nucleic acids.

Abstract Two Dimensional COSY and HETCOR experiments have been performed on the alkaloid vindoline which allow the complete 1zH and 13C spectral assignments to be made. Proton-proton and proton-carbon coupling constants are also given.

In typical NMR experiments 90 percent of the time is used for doing nothing. It is necessary to wait until sufficient polarization is recovered for the next scan. Many tricks have been developed during decades of NMR spectroscopy. The first systematic study involved the use of β-pulses, i.e.
