A robust, deep learning-based analysis of time-domain signals for NMR spectroscopy

Journal of Analytical Science and Technology
When analyzing the Free Induction Decay (FID) signal produced by nuclear magnetic resonance (NMR) spectroscopy, Fourier transforms (FT) are used to decompose time-domain signals arising from nuclear interactions.

Ion and polymer dynamics in polymer electrolytes PPO-LiClO4: insights from NMR line-shape analysis

, 2006
We investigate ion and polymer dynamics in polymer electrolytes PPO-LiClO4 performing 2H and 7Li NMR line-shape analysis. Comparison of temperature dependent 7Li and 2H NMR spectra gives evidence for a coupling of ion and polymer dynamics. 2H NMR spectra

Transient and steady-state shear banding in a lamellar phase as studied by Rheo-NMR [PDF]

, 2012
Flow fields and shear-induced structures in the lamellar (L-alpha) phase of the system triethylene glycol mono n-decyl ether (C10E3)/water were investigated by NMR velocimetry, diffusometry, and H-2 NMR spectroscopy. The transformation from multilamellar

Evolution of Paramagnetic Quasiparticle Excitations Emerged in the High-Field Superconducting Phase of CeCoIn5 [PDF]

, 2011
We present In NMR measurements in a novel thermodynamic phase of CeCoIn5 in high magnetic field, where exotic superconductivity coexists with the incommensurate spin-density wave order.

Antiferromagnetism of SrFe2As2 studied by Single-Crystal 75As-NMR

, 2009
We report results of 75As nuclear magnetic resonance (NMR) experiments on a self-flux grown high-quality single crystal of SrFe2As2. The NMR spectra clearly show sharp first-order antiferromagnetic (AF) and structural transitions occurring simultaneously.

Effect of charged lipids on the ionization behavior of glutamic acid containing transmembrane helices [PDF]

, 2020
Transmembrane proteins make up critical components of living cells. Protein function can be greatly impacted by the charged state of its respective components, the side chains of amino acid residues.

Improved classification accuracy in 1- and 2-dimensional NMR metabolomics data using the variance stabilising generalised logarithm transformation

BMC Bioinformatics, 2007
Background Classifying nuclear magnetic resonance (NMR) spectra is a crucial step in many metabolomics experiments. Since several multivariate classification techniques depend upon the variance of the data, it is important to first minimise any ...

Nuclear magnetic resonance and infrared spectra of Δ24- and C-24 saturated steroids

Journal of Lipid Research, 1968
The infrared (IR) and nuclear magnetic resonance (NMR) spectra of eight Δ24-steroids and nine C-24 saturated steroids were examined. NMR spectra allow unambiguous assignment of the biologically important Δ24-bond; introduction of a Δ24-bond causes the ...
