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

Orientational distribution of polymer chains studied by 2H n.m.r. line shapes
TL;DR: In this article, a simple method for computing magnetic resonance line shapes by superposition of a relatively small number of subspectra, which can in turn be calculated analytically, is described.

Acyl chain orientational order in the hexagonal HII phase of phospholipid-water dispersions.
TL;DR: It is suggested that as a consequence of the geometrical characteristics of the HII phase, there is an increase in conformational freedom available to different parts of the acyl chain.

Effect of hydration upon the fluidity of intercellular membranes of stratum corneum: an EPR study.
TL;DR: This work evaluates the effect of hydration on the fluidity of intercellular membranes at three depths of the alkyl chain using the spin labeling method to give a better characterization of the fluidities of SC, the main parameter involved in the mechanisms that control the permeability of different compounds through skin.

High pressure 2H nuclear magnetic resonance study of the gel phases of dipalmitoylphosphatidylcholine.
TL;DR: The 2H-NMR lineshapes of dipalmitoylphosphatidylcholine perdeuterated in the acyl chains were studied in a 15% dispersion in water as a function of pressure from 1 bar to 5 kbar over the temperature range from 7 degrees C to 75 degrees C.

Distorted structure of the retinal chromophore in bacteriorhodopsin resolved by 2H-NMR.
TL;DR: The deduced geometry confirms and refines the known structural information on the chromophore, suggesting that this 2H-NMR strategy may serve as a valuable tool for other membrane proteins.

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.
