Solid State Nuclear Magnetic Resonance
In 2001, Mauri and Pickard introduced the gauge including projected augmented wave (GIPAW) method that enabled for the first time the calculation of all-electron NMR parameters in solids, i.e. accounting for periodic boundary conditions. The GIPAW method roots in the plane wave pseudopotential formalism of the density functional theory (DFT), and avoids the use of the cluster approximation. Thi...
متن کاملSolid-state nuclear magnetic resonance.
SCOPE This review focuses on developments and applications in the field of nuclear magnetic resonance of solids appearing in the literature between October 1999 and October 2001. The review emphasizes uses of solid-state NMR spectroscopy to answer questions about problems in certain areas of chemistry and materials science. As time passes, the use of solid-state techniques to address problems i...
متن کاملSolid State Nuclear Magnetic Resonance
A H–C frequency-selective REDOR (FS-REDOR) experiment is developed for measuring intramolecular H–C distances in uniformly C, N-labeled molecules. Theory and simulations show that the experiment removes the interfering homonuclear H–H, C–C and heteronuclear H–N, C–N dipolar interactions while retaining the desired heteronuclear H–C dipolar interaction. Our results indicate that this technique, ...
متن کاملHigh-resolution liquid- and solid-state nuclear magnetic resonance of nanoliter sample volumes using microcoil detectors.
The predominant means to detect nuclear magnetic resonance (NMR) is to monitor the voltage induced in a radiofrequency coil by the precessing magnetization. To address the sensitivity of NMR for mass-limited samples it is worthwhile to miniaturize this detector coil. Although making smaller coils seems a trivial step, the challenges in the design of microcoil probeheads are to get the highest p...
متن کاملMembrane Disordering by Eicosapentaenoic Acid in B Lymphomas Is Reduced by Elongation to Docosapentaenoic Acid as Revealed with Solid-State Nuclear Magnetic Resonance Spectroscopy of Model Membranes.
BACKGROUND Plasma membrane organization is a mechanistic target of n-3 (ω-3) polyunsaturated fatty acids. Previous studies show that eicosapentaenoic acid (EPA; 20:5n-3) and docosahexaenoic acid (DHA; 22:6n-3) differentially disrupt plasma membrane molecular order to enhance the frequency and function of B lymphocytes. However, it is not known whether EPA and DHA affect the plasma membrane orga...
