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

A deuterium NMR study of labelled n-alkanol anesthetics in a model membrane
TL;DR: Variation of the spectral moments M1 with temperature indicates that both 1-decanol and 1-octanol are sensitive to the packing of the lipid in which they are dissolved, which implies that the phospholipid acyl chain conformations are more restricted than those of the alcohol at these temperatures.

Cubic topology in surfactant and lipid mixtures
TL;DR: In this article, an epitaxial relationship between all three phases was found, which is an elegant and convenient way to rearrange molecules from lamellar bilayers to a network of curved surfaces.

Alkyl Chain Flexibility in Liquid Crystals
TL;DR: In this paper, several parameters for quantifying alkyl chain flexibility are examined for free, unrestricted chains as a function of temperature, and the constraints imposed on alkyls chains in uniaxial liquid crystals are modeled.

Spin label and 2H-NMR studies on the interaction of melanotropic peptides with lipid bilayers
TL;DR: Changes in the α-deuteron quadrupolar splittings and spin lattice relaxation time of DMPG deuterated at the glycerol headgroup paralleled the results obtained with ESR, showing that the peptides cause a better packing both at the headgroup and at the acyl chain bilayer regions.

Structure and motion of phospholipids in human plasma lipoproteins. A 31P NMR study.
TL;DR: The large increase in diffusion rate observed in LDL occurs over the same temperature range as the smectic to disordered phase transition of the core cholesteryl esters, and provides evidence for direct interactions between the monolayer and core.

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.
