Comparative study of the vibrational optical activity techniques in structure elucidation : the case of galantamine [PDF]
The absolute configuration of the alkaloid galantamine was studied using a range of solution-state techniques; nuclear magnetic resonance (NMR), vibrational circular dichroism (VCD), and Raman optical activity (ROA). While the combined use of NMR and VCD

MetAssimulo:Simulation of Realistic NMR Metabolic Profiles
Background Probing the complex fusion of genetic and environmental interactions, metabolic profiling (or metabolomics/metabonomics), the study of small molecules involved in metabolic reactions, is a rapidly expanding 'omics' field. A major technique for

Correlation of high-field and zero- to ultralow-field NMR properties using 2D spectroscopy [PDF]
The field of zero- to ultralow-field (ZULF) nuclear magnetic resonance (NMR) is currently experiencing a rapid growth, owing to the progress in optical magnetometry, and also attractive features of ZULF NMR, such as low hardware cost and excellent spectral resolution achieved under ZULF conditions. In this work, an approach is proposed and demonstrated

Automated quality control for proton magnetic resonance spectroscopy data using convex non-negative matrix factorization [PDF]
Proton Magnetic Resonance Spectroscopy (1H MRS) has proven its diagnostic potential in a variety of conditions. However, MRS is not yet widely used in clinical routine because of the lack of experts on its diagnostic interpretation.

13C NMR Spectral Prediction by Means of Generalized Atom Center Fragment Method
Knowledge-based NMR spectral prediction relies on the correlations between substructures and sub-spectra. To extract the correlations, a systematic substructure measurement has been developed to classify substructures according to their chemical shift ...

Software Tools and Approaches for Compound Identification of LC-MS/MS Data in Metabolomics. [PDF]
The annotation of small molecules remains a major challenge in untargeted mass spectrometry-based metabolomics. We here critically discuss structured elucidation approaches and software that are designed to help during the annotation of unknown compounds.

Resonance assignments for latherin, a natural surfactant protein from horse sweat [PDF]
Latherin is an intrinsically surfactant protein of ~23 kDa found in the sweat and saliva of horses. Its function is probably to enhance the translocation of sweat water from the skin to the surface of the pelt for evaporative cooling.

Mushroom and cereal β-D-glucan solid state NMR and FTIR datasets
In the associated published article Kremmyda et al. (2021), the C1 region of the NMR spectra were examined in detail, as the C1 carbon was common to the crucial linkages in the glucan, and the most clearly separated region in the spectra.
