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

Conformational changes of the phosphatidylcholine headgroup due to membrane dehydration. A 2H-NMR study.
TL;DR: The conformational change induced by the loss of water molecules at the membrane surface is qualitatively similar to that observed upon addition of polyhydroxyl compounds.

Conformation of phospholipids. Crystal structure of a lysophosphatidylcholine analogue.
TL;DR: A close resemblance to the gel state of lysoph phosphatidylethanolamine and diacylphosphatidylcholine is found which now allows a detailed interpretation of the molecular conformation and packing principles in the fully hydrated lamellar structures of these important membrane lipids.

TL;DR: A comprehensive database of NMR results for membrane phospholipids with interpretations intended to be accessible by non-NMR specialists, which suggests that lipid diffusion and collective order fluctuations are implicitly governed by the viscoelastic nature of the liquid-crystalline ensemble.

TL;DR: With the interpretations of the molecular packing and the phase structures, the observed phase equilibria are in good agreement with current theories of the factors that govern phase behavior in amphiphile--water systems.

Interaction of electric dipoles with phospholipid head groups. A 2H and 31P NMR study of phloretin and phloretin analogues in phosphatidylcholine membranes.
TL;DR: In this paper, the structural changes at the level of the head groups and the hydrocarbon chains as induced by the incorporation of phloretin and its analogues were investigated with deuterium and phosphorus nuclear magnetic resonance.

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.
