Phosphorus chemical shift tensors in dithiadiphosphetane disulfides determined by solid-state 31P nuclear magnetic resonance.
The phosphorus chemical shift tensors of two dithiadiphosphetane disulfides, 2,4-bis(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4-di sulfide (1) and 2,4-bis(methylthio)-1,3-dithia-2,4-diphosphetane-2,4-disu lfi de (2), have been characterized by solid-state 31P nuclear magnetic resonance (NMR) measurements. The weak homonuclear dipolar interaction between the two 31P nuclei in each of thes...

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...

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 کاملTryptophan chemical shift in peptides and proteins: a solid state carbon-13 nuclear magnetic resonance spectroscopic and quantum chemical investigation.
We have obtained the carbon-13 nuclear magnetic resonance spectra of a series of tryptophan-containing peptides and model systems, together with their X-ray crystallographic structures, and used quantum chemical methods to predict the (13)C NMR shifts (or shieldings) of all nonprotonated aromatic carbons (C(gamma), C(delta 2) and C(epsilon 2). Overall, there is generally good accord between the...
