Increasing the accuracy of structural investigations by MAS spin-echo solid-state NMR experiments
The use of rotor-synchronized Hahn-echo pulse train (RS-HEPT) H decoupling, in a MAS (Magic Angle Spinning) N spin-echo NMR experiment allows the use of longer the spin-echo durations compared to the case when conventional decoupling is applied, hence enabling the accurate determination of very small J couplings down to a few Hz. Here, a thorough numerical analysis of the N spin-echo under RS-H...
متن کاملStructural Characterization of Hydrothermal Carbon Spheres by Advanced Solid-State MAS 13 C NMR Investigations
The local structure of carbon spheres obtained via the hydrothermal carbonization process is characterized by using a combination of advanced solid-state 13C NMR techniques. Glucose was chosen as the starting product because it offers the possibility of 13C isotopic enrichment and is regarded as a model compound for more complex polysaccharides and biomass, as reported in recent studies. A numb...
متن کاملA software framework for analysing solid-state MAS NMR data
Solid-state magic-angle-spinning (MAS) NMR of proteins has undergone many rapid methodological developments in recent years, enabling detailed studies of protein structure, function and dynamics. Software development, however, has not kept pace with these advances and data analysis is mostly performed using tools developed for solution NMR which do not directly address solid-state specific issu...
متن کاملMAS solid-state NMR studies on the multidrug transporter EmrE.
We study the uniformly 13C,15N isotopically enriched Escherichia coli multidrug resistance transporter EmrE using MAS solid-state NMR. Solid-state NMR can provide complementary structural information as the method allows studying membrane proteins in their native environment as no detergent is required for reconstitution. We compare the spectra obtained from wildtype EmrE to those obtained from...
متن کاملOptimized multiple quantum MAS lineshape simulations in solid state NMR
The majority of nuclei available for study in solid state Nuclear Magnetic Resonance have half-integer spin I > 1/2, with corresponding electric quadrupole moment. As such, they may couple with a surrounding electric field gradient. This effect produces anisotropic line broadening in spectra for distinct chemical species in polycrystalline solids. In Multiple Quantum Magic Angle Spinning (MQMAS...
