TLDR
Proton and carbon-13 nmr spectra of unsonicated lipid bilayers and biological membranes are generally dominated by strong proton-proton and proton–carbon dipolar interactions and are rather difficult to analyse.Abstract:
Proton and carbon-13 nmr spectra of unsonicated lipid bilayers and biological membranes are generally dominated by strong proton–proton and proton–carbon dipolar interactions. As a result the spectra contain a large number of overlapping resonances and are rather difficult to analyse. Nevertheless, important information on the structure and dynamic behaviour of lipid systems has been provided by these techniques (Wennerstrom & Lindblom, 1977).read more

TL;DR: The results clearly show that charged lidocaine affects significantly the lipid headgroup, in particular the ordering of the lipids is increased accompanied by drastic changes in the orientation of the P-N vector in the choline group.

TL;DR: The orientation of prosthetic groups in membrane proteins is of considerable importance in understanding their functional role in energy conversion, signal transduction, and ion transport and in this work, the orientation of the retinylidene chromophore of bacteriorhodopsin was investigated using 2H NMR spectroscopy.

Segmental Dynamics in Poly(methyl Acrylate) on Silica: Effect of Surface Treatment
Burak Metin,Frank D. Blum +1 more
TL;DR: The dynamics on treated silica showed a broad heterogeneity with a superposition of more-mobile and less-mobile components, with the molecular mass dependence on the treated or untreated silica being weaker than that in bulk.

Deuterium magnetic resonance study of cholesteryl esters in membranes.
TL;DR: The ternary systems EYL:H2O (50:50 wt %) containing 1 and 5 mol % cholesteryl palmitate-d31 or 1 and5 mol % Cholesteryl Palmitate -16,16, 16,16-d3 have been studied and the most probable order parameter for the (-CD2)n portion of the homogeneous fraction of cholesteryle ester in bilayers was determined.

Magnetic alignment and orientational order of dipalmitoylphosphatidylcholine bilayers containing palmitoyllsyophosphatidylcholine
TL;DR: The mixed liquid-crystalline bilayers orient preferentially with their director axes perpendicular to the magnetic field, and one possible explanation of the magnetic alignment involves alteration of the curvature free energy of the DPPC bilayer due to incorporation of PaLPC in the mixed membranes.

Principles of magnetic resonance
TL;DR: In this article, the effect of changing the precession frequency of the magnetic field has been studied using NMR to study rate properties. But the effect is limited to the case of double and double resonance.
