The molecular dynamics of a series of organometallic complexes covalently bound to amorphous silica surfaces is determined experimentally using solid-state nuclear magnetic resonance (NMR) spectroscopy and density functional theory calculations (DFT). The ...
The phenomenon of magnetism is one of the key components of today's technological progress. Magnetic interactions and magnetic materials are essential for the scientific disciplines of physics, chemistry and biology, making this subject truly multidiscipli ...
Since many biological processes occur on the μs to ms time scale, internal dynamics on that time scale may well be related to biological functionality. The characterization of internal dynamics is thus an important issue to improve our understanding of the ...
In order to relate the conformational dynamics of the hammerhead ribozyme to its biological function the cleavage reaction catalyzed by the hammerhead ribozyme was monitored by time-resolved nuclear magnetic resonance (NMR) spectroscopy. For this purpose, ...
A refocused INEPT through-bond coherence transfer technique is demonstrated for NMR of rigid organic solids and is shown to provide a valuable building block for the development of NMR correlation experiments in biological solids. The use of efficient prot ...
The molecular dynamics of [-SiDMe(2)] grafted on two amorphous silica materials, mesoporous SBA and non-porous Aerosil, was investigated by deuteron ((2)H) solid-state NMR spectroscopy. Quadrupole echo (QE), quadrupole Carr-Purcell-Meiboom-Gill (QCPMG) and ...
When applying multiple refocusing pulses to characterize the cross-correlated relaxation of heteronuclear multiple quantum coherence 2NxHx in biomols., the unavoidable effects of pulse imperfections are compensated by the scalar couplings between nitrogen ...
Since many biological processes occur on the μs to ms time scale, internal dynamics on that time scale is believed to be related to biological functionality. The characterization of internal dynamics is thus an important issue to improve our understanding ...
Water-protein interactions play a major role in protein folding, structure, and function, and solid-state NMR has recently been shown to be a powerful tool for the site-resolved observation of these interactions in solid proteins. In this article we report ...
We show how high-resolution NMR spectra can be obtained for solids for which the spectra are normally broadened due to structural disorder. The method relies on correlations in the chemical shifts between pairs of coupled spins. It is found experimentally ...
