As opposed to traditional NOE based NMR structure determinations, RDCs provide long distance structural information. It also provides information about the dynamics in molecules on time scales … See more The residual dipolar coupling between two spins in a molecule occurs if the molecules in solution exhibit a partial alignment leading to an incomplete averaging of spatially anisotropic dipolar couplings. Partial molecular … See more The secular dipolar coupling Hamiltonian of two spins, $${\displaystyle I}$$ and $${\displaystyle S,}$$ is given by: where See more • Magnetic dipole–dipole interaction • Residual chemical shift anisotropy (rCSA) • Solid-state nuclear magnetic resonance (ssNMR) See more NMR spectroscopy in partially oriented media was first discovered in 1963, and in a very fundamental paper Alfred Saupe was also able to present the essential theory to describe and understand the observable phenomena only one year later.

WebJan 20, 2016 · Following the recent success in the determination of relative and absolute configuration of flexible and complex organic molecules by using a combination of residual dipolar coupling (RDC)-based NMR spectroscopy [ 9 – 15] and chiroptics [ 16 – 19 ], the complete stereochemistry and preferred conformation of fusariumin A has been … WebOct 31, 2012 · Large Proteins. Large proteins give worse NMR spectra, because they tumble more slowly. For this reason the CBCANNH and CBCA (CO)NNH spectra of larger proteins (> 150 residues) are often not of sufficient quality to be able to carry out a full assignment. In this case a good option is the use of HNCA, HN (CO)CA, HNCO and HN (CA)CO spectra. optifine textures download
