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

Deuteron NMR Study of Molecular Mobility in a Polymer Model Membrane
R. Ebelhäuser,H. W. Spiess +1 more
TL;DR: In this article, the molecular mobility of a polymer model membrane is studied by 2H NMR and the data are quantitatively analyzed in terms of a simple motional model, in which the complex molecular dynamics is approximated by a six-site jump model describing rotations about the long axis of the molecule and conformational changes.

Deuterium NMR of 2HCO-Val1...gramicidin A and 2HCO-Val1-D-Leu2...gramicidin A in oriented DMPC bilayers.
TL;DR: Deuterium NMR line shapes obtained from these samples indicate that the motional axis of the formyl group of gramicidin is parallel to the coverslip normal, that the distribution of motionalaxis orientations has a width of 7-9 degrees, and that a similar, major conformational and dynamical state exists for theFormyl C-2H bond of both analogues.

Effect of a Polar Environment on the Conformation of Phospholipid Head Groups Analyzed with the Onsager Continuum Solvation Model
TL;DR: In this paper, the effect of the polarity of the environment on the conformation of the zwitterionic membrane lipid head groups was investigated with calculations at the Hartree−Fock level using the 3-21G*, 6-31G*, and 6- 31+G* basis sets together with the Onsager continuum solvation model.

Dioxygen transmembrane distributions and partitioning thermodynamics in lipid bilayers and micelles.
TL;DR: The detailed distribution of oxygen across lipid bilayers is reported and the thermodynamics of oxygen partitioning via NMR studies of lipids in a small unilamellar vesicle (SUV) morphology is examined.

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.
