Structure and Intramolecular Mobility of Some Derivatives of Bis(thio)phosphorylated Amides in CD₂Cl₂ and CD₃CN Solutions

Учёные записки Казанского университета: Серия Естественные науки, 2023
The structure and intramolecular mobility of some derivatives of bis(thio)phosphorylated amides in CCl4, CD2Cl2, and CD3CN solutions were examined by 1H and 31P NMR spectroscopy.

Hydrophobic double walled carbon nanotubes interaction with phopholipidic model membranes: 1H-, 2H-, 31P NMR and ESR study [PDF]

, 2010
The interactions of carbon nanotubes synthesized by catalytic chemical vapour deposition with phospholipidic bilayers, mimicking biological membranes, have been investigated using solid state 31P- and 2H NMR, 1H- and 31P NMR in liquids and ESR studies ...

Complex Mixture Analysis of Organic Compounds in Yogurt by NMR Spectroscopy

Metabolites, 2016
NMR measurements do not require separation and chemical modification of samples and therefore rapidly and directly provide non-targeted information on chemical components in complex mixtures.

Investigating Relationships between the Crystal Structure and 31P Isotropic Chemical Shifts in Calcined Aluminophosphates [PDF]

, 2014
Solid-state NMR spectra have historically been assigned using simple relationships between NMR parameters, e.g., the isotropic chemical shift, and aspects of the local structure of the material in question, e.g., bond angles or lengths.

Hepatic metabolism by 31P NMR

Bioscience Reports, 1982
Hepatic metabolism in intact livers has been studied by 31P nuclear magnetic resonance (NMR) spectroscopy. 31P NMR spectroscopy of normal liver detects little ADP and much lower amounts of inorganic phosphate than are found by enzymatic or chemical analysis.

Improvement of quantitative solution 31P NMR analysis of soil organic P: a study of spin–lattice relaxation responding to paramagnetic ions

Geochemical Transactions, 2020
Solution 31P nuclear magnetic resonance (NMR) spectroscopy has been widely applied to analyze the speciation of soil organic P; however, this time-consuming technique suffers from a low analytical efficiency, because of the lack of fundamental ...

Contribution of protein phosphorylation to binding-induced folding of the SLBP–histone mRNA complex probed by phosphorus-31 NMR

FEBS Open Bio, 2014
Phosphorus-31 (31P) NMR can be used to characterize the structure and dynamics of phosphorylated proteins. Here, I use 31P NMR to report on the chemical nature of a phosphothreonine that lies in the RNA binding domain of SLBP (stem-loop binding protein).

NMR of 31P in CrRuP

Journal of the Magnetics Society of Japan, 1999
NMR properties of 31P in CrRuP at low temperatures are reported. The compound CrRuP, which is a member of a series of compounds MRuP (M=3d transition metal), was expected to be in a nonmagnetic state at low temperature such as a Kondo insulator from the susceptibility data.
