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

19F nuclear magnetic resonance studies of lipid fatty acyl chain order and dynamics in Acholeplasma laidlawii B membranes. Orientational order in the presence of a series of positional isomers of cis-octadecenoic acid.
TL;DR: In this article, the 19F NMR spectra of membranes of Acholeplasma laidlawii B enriched with one of a series of positional isomers of cis-octadecenoic acid plus small amounts of monofluoropalmitic acid were interpreted in terms of an orientational order parameter (Smol).

Two-dimensional solid-state NMR applied to a chimeric potassium channel.
TL;DR: Two-dimensional correlation experiments conducted on a fully [13C,15N] labeled version of a chimeric potassium (KcsA-Kv1.3) channel suggest a structural conservation of the selectivity filter region.

TL;DR: Structural parameters including the area per lipid, total bilayer thickness, and hydrocarbon thickness, in addition to lipid volumes determined by densitometry are reported, using a newly developed scattering density profile (SDP) model for sphingomyelin lipids.

Domains in cationic lipid plus polyelectrolyte bilayer membranes: detection and characterization via 2H nuclear magnetic resonance.
TL;DR: 2H nuclear magnetic resonance (NMR) spectroscopy has been used to detect and quantify domain formation induced in cationic lipid-containing bilayers upon the addition of anionic polyelectrolytes, revealing a constant number of bound DODAP but a flexible number of Bound POPC, which increased in proportion to the global POPC content.

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.
