Dynamic communication between atoms within folded proteins is potentially important for function, but its measurement has been a challenge. Now, a combined NMR and modelling study provides insights on the presence and strengths of such correlations.

We show how (27)Al-(13)C proximities in the microporous metal-organic framework MIL-100(Al) can be probed using advanced (27)Al-(13)C NMR methods boosted by Dynamic Nuclear Polarization.

The surface of γ-alumina nanoparticles can be characterized by dynamic nuclear polarization (DNP) surface-enhanced NMR of (27)Al. DNP is combined with cross-polarization and MQ-MAS to determine local symmetries of (27)Al sites at the surface.

$^{139}$La nuclear magnetic resonance (NMR) measurements under pressure ($p = 0-2.64$ GPa) have been carried out to investigate the static and dynamic properties of itinerant ferromagnet LaCrGe$_3$. $^{139}$La-NMR spectra for all measured pressures in ferromagnetically ordered state show a large shift due internal field induction $|$$B_{\rm int}$$|$ $\sim$ 4 T at La site produced by Cr moments....

The tendency to reach dynamic equilibrium of intercluster reaction, Ag7(H) and Cu7(H), in solution is driven by a stepwise, one-metal exchange process, which has been illustrated 2D EXSY NMR experiments.

Reactions of the aminoiminophenols 2-((2-(dimethylamino)ethylimino)methyl)phenol (HL(1)) or 2-{(3-(dimethylamino)propylimino)methyl}phenol (HL(2)) with nickel(II) chloride, K(2)[PtCl(4)] or copper(II) acetate in alcoholic solution, in the absence or in the presence of sodium azide, afford the corresponding new mononuclear complexes [M(L(1))(X)(H(2)O)(n)] [M = Ni, X = Cl(-), n = 2 (); M = Ni, X ...

Series of polynuclear diorganotin(IV) complexes with di-halogenbenzohydroxamate ligands (substituents=2,4-Cl(2), 2,4-F(2), 3,4-F(2), 2,5-F(2), 2,6-F(2)), formulated as the polymeric [R(2)SnL](n)a (1:1) and the tetranuclear [R(4)Sn(2)(HL)(2)(L)](2)b (2:3) (HL=arylhydroxamate), were prepared and characterized by FT-IR, (1)H, (13)C, (119)Sn NMR spectroscopies, elemental analyses and melting point ...

Ribonucleoprotein (RNP) complexes are involved in several cellular processes, including RNA processing, transcription and translation. RNP structures are often dynamic in nature, undergoing significant remodeling during the course of their function. Visualization of the three-dimensional arrangement of single components in the complex and characterization of the intermolecular interactions are ...

porphyrins are a ubiquitous large class of naturally occurring macrocyclic compounds with many significant biological representatives comprising heme and chlorophyll. some novel adaptable methods for the synthesis of free-based porphyrins as promising sensitizers for the use in photo-dynamic therapy by the virtue of their known tumor affinity, low dark cytotoxicity, and easy synthesis in good t...

The excellent results of dispersion-corrected density functional theory (DFT-D) calculations for static systems have been well established over the past decade. The introduction of dynamics into DFT-D calculations is a target, especially for the field of molecular NMR crystallography. Four (13) C ss-NMR calibration compounds are investigated by single-crystal X-ray diffraction, molecular dynami...
