Transient association of ethanol with magnetically aligned bicelles imparts a small degree of anisotropy to the solute. This anisotropy allows detection of residual (1)H-(1)H and (1)H-(13)C dipolar couplings, which are superimposed on scalar couplings. Residual (2)H NMR quadrupole splittings of isotope-labeled ethanol were measured as well. The analysis of residual tensorial interactions yielded information on the orientation and motions of ethanol in the membrane-bound state. The fraction of phosphatidylcholine-bound ethanol was determined independently by gas chromatography and NMR. About $4\%$ of ethanol is bound to phosphatidylcholine at a bicelle concentration of 14 wt $\%$ at 40 degrees C. Free and bound ethanol are in rapid exchange. The lifetime of ethanol association with phosphatidylcholine membranes is of the order of a few nanoseconds.}, keywords = {Chemistry, Physical: methods / Chromatography, Gas / Dimyristoylphosphatidylcholine: chemistry / Ethanol: chemistry / Lipid Bilayers / Lipids: chemistry / Magnetic Resonance Spectroscopy / Molecular Conformation / Phosphatidylcholines: chemistry / Phospholipids: chemistry / Time Factors / Lipid Bilayers (NLM Chemicals) / Lipids (NLM Chemicals) / Phosphatidylcholines (NLM Chemicals) / Phospholipids (NLM Chemicals) / Dimyristoylphosphatidylcholine (NLM Chemicals) / Ethanol (NLM Chemicals) / J (WoSType)}, cin = {IBI-2}, ddc = {530}, cid = {I:(DE-Juel1)VDB58}, pnm = {Neurowissenschaften}, pid = {G:(DE-Juel1)FUEK255}, shelfmark = {Chemistry, Physical}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:16851866}, UT = {WOS:000228419100088}, doi = {10.1021/jp044980b}, url = {https://juser.fz-juelich.de/record/45561}, }
