Re-protonation is key: A combination of a high magnetic field (1 GHz) and ultra-fast magic-angle spinning (60 kHz) allows easy detection of NMR spectra revealing details of secondary and tertiary structures of medium-sized proteins. The technique was appli ...
In solids spinning at the magic angle, the indirect detection of single-quantum (SQ) and double-quantum (DQ) N-14 spectra (l = 1) via spy nuclei S = 1/2 such as protons can be achieved in the manner of heteronuclear single- or multiple-quantum correlation ...
Isotropic chemical shifts and quadrupole coupling parameters of Se-77 and Ge-73 nuclei in GeSe2 and GeSe4 glasses are determined through density-functional NMR calculations on amorphous model structures generated by ab initio molecular dynamics. The compar ...
Supervised multivariate statistical analyses of NMR spectroscopic data sets are often required to identify metabolic differences between sample classes, and 20 the use of orthogonal filters has proven to be highly efficient even when dealing with weak pert ...
Long-lived coherences (LLCs) in homonuclear pairs of chemically inequivalent spins can be excited and sustained during protracted radio frequency irradiation periods that alternate with brief windows for signal observation. Fourier transformation of the su ...
We investigate the combined effect of perdeuteration and fast magic-angle spinning on the resolution and sensitivity of proton-detected protein NMR spectra and on coherence lifetimes. With 60 kHz spinning of a microcrystalline alpha-spectrin SH3 sample at ...
The synthesis and in vitro anticancer activity of OsII-arene complexes with carbohydrate-derived phosphite co-ligands are reported. The compds. were characterized by std. methods and the mol. structure of dichlorido(η6-p-cymene)(3,5,6-bicyclophosphite-1,2- ...
Unambiguous identification of individual metabolites present in complex mixtures such as biofluids constitutes a crucial prerequisite for quantitative metabolomics, toward better understanding of biochemical processes in living systems. Increasing the dime ...
We present a new phase modulated radio-frequency pulse sequence for homonuclear dipolar decoupling in proton solid-state NMR spectroscopy, eDUMBO-PLUS-1, with a chemical shift scaling factor of 0.73. This sequence was determined by screening random sequenc ...
A drastic reduction of the time required for two-dimensional NMR experiments can be achieved by reducing or skipping the recovery delay between successive experiments. Novel SMAll Recovery Times (SMART) methods use orthogonal pulsed field gradients in thre ...
