Full relaxation matrix analysis of apparent cross-correlated relaxation rates in four-spin systems
Full relaxation matrix analysis of apparent cross-correlated relaxation rates in four-spin systems
January 2013
Publication year: 2013
Source:Journal of Magnetic Resonance, Volume 226</br>

Cross-correlated relaxation (CCR) rates are an established tool for the extraction of relative bond orientations in biomolecules in solution. CCR between dipolar interactions in four-spin systems is a particularly well-suited mechanism. In this paper, a simple approach to analyze systematic experimental errors is formulated in a subspace of the complete four-spin Hilbert space....

13C relaxation experiments for aromatic side chains employing longitudinal- and transverse-relaxation optimized NMR spectroscopy
13C relaxation experiments for aromatic side chains employing longitudinal- and transverse-relaxation optimized NMR spectroscopy
Abstract Aromatic side chains are prevalent in protein binding sites, perform functional roles in enzymatic catalysis, and form an integral part of the hydrophobic core of proteins. Thus, it is of great interest to probe the conformational dynamics of aromatic side chains and its response to biologically relevant events. Indeed, measurements of 13C relaxation rates in aromatic moieties have a long history in biomolecular NMR, primarily in the context of...
[Question from NMRWiki Q&A forum] Relaxation editing vr paramagnetic relaxation enhancement experiments - 13C CP-MAS NM
Relaxation editing vr paramagnetic relaxation enhancement experiments - 13C CP-MAS NMR
I am a beginner in NMR spectroscopy and I would like to learn more about relaxation editing experiments vs PRE. A colleague of mine is doing the 13C CP-MAS NMR experim. and he using cellulose II powder, regenerated cellulose and milled reg cellulose. We are interested in C4 resonance of cellulose II, good resolved resonance, to better understand the supramolecular structure of cellulose II. As experiments: long relaxation experiments - PRE with aqueous CuSO4 solution of certain concentration, does the...
