The shapes of NMR absorption lines, free induction decays, and Jeener echoes in systems such as lyotropic liquid crystals have been investigated theoretically and experimentally. For a system having an axis of symmetry for the molecular motion which

Deuterium magnetic resonance (DMR) spectra of the water and hydrocarbon chains in potassium and sodium palmitates and sodium magnetic resonance spectra of sodium in sodium palmitate demonstrate correlations between water, hydrocarbon chain and counte

The quadrupolar spin echo from deuterons in ordered hydrocarbon systems is shown to provide a much more reliable spectrum than the conventional free induction decay Fourier transform. Spectrometer dead time is eliminated, phase correction uncertainti

Dispersions (50 wt% in water) of sphingomyelin/cholesteryl palmitate (95 : 5 mol%) have been studied by 2H- and 31P-NMR spectroscopy between 25 and 60 degrees C. The deuterated esters, cholesteryl palmitate-d31 and cholesteryl palmitate-16, 16, 16-d3

Proton magnetic resonance (1H NMR) has been used to compare the local orientational order of acyl chains in phospholipid bilayers of multilamellar and small sonicated vesicular membranes of dipalmitoyllecithin (DPL) at 50 degrees C and egg yolk lecit

The quadrupolar echo Fourier transform technique effectively eliminates spectral distortion in deuterium nuclear magnetic resonance (2H nmr) spectroscopy due to the finite time required for recovery of the rf receiver following the application of an

Dispersions (50 wt% water) containing 95 mol% dipalmitoyl phosphatidylcholine/5 mol% deuterated cholesteryl palmitate (or stearate) were studied using 2H-NMR. Incorporation of ester into the phospholipid bilayer was found to be 0.5 mol% at 50 degrees

The ternary systems EYL:H2O (50:50 wt %) containing 1 and 5 mol % cholesteryl palmitate-d31 or 1 and 5 mol % cholesteryl palmitate-16,16,16,16-d3 have been studied. Cholesteryl palmitate-d31 gave a unique deuterium magnetic resonance spectrum corresp

Several experimenters [ l-41 have reported that the methylene proton magnetic resonance (PMR) linewidth in small single bilayer vesicles is constant for a wide range of viscosities. They have consequentially inferred that the only molecular motions r
