}Abstract. Spin label hyperfine splittings in mixtures of protic and aprotic solvents are used to obtain association constants KA,h for hydrogen bonding to oxazolidine nitroxides. With the Onsager approach to account for the variation in local dielectric constant, these results are used to determine the effective penetration profile of water into fluid phospholipid membranes, from recent electron paramagnetic resonance (EPR) studies on phospholipids spin-labelled systematically down the sn-2…

The results show that in curved vesicles lacking cholesterol, the label attached to carbon 16 may travel as far high along the membrane normal as the location of the label on carbon 5, due to the presence of U-shaped lipid conformations.

Two-pulse, echo-detected electron paramagnetic resonance (EPR) spectroscopy was used to study the librational motions of spin-labeled lipids in membranes of dipalmitoylphosphatidylcholine + 50 mol % cholesterol, which are important for glass-like states and are generally relevant to high lipid packing densities, e.g., in cholesterol-containing raft domains and condensed complexes.

The experimental technique which permits highly sensitive spectroscopy as previously demonstrated for surfactant mixtures is described and its capability in the study of partitioning of cosurfactant molecules in surfactants bilayers is demonstrated in order to elucidate the main factors which contribute to cosurFactant ordering at interfaces.

The results are relevant not only to the permeation of water and polar solutes into membranes and their permeabilities, but also to depth determinations of site-specifically spin-labeled protein residues by using paramagnetic relaxation agents.
