摘要：

The nonionic surfactant hexa(ethyleneglycol) n-dodecyl methylether in aqueous liquid-crystalline phases is studied by deuterium NMR spectroscopy. From the quadrupole splittings of the surfactant, which is deuterated either in the hydrophobic alkyl chain or in the hydrophilic oxyethylene chain, order profiles of both the alkyl and oxyethylene moiety are obtained. Characteristic features of the order profiles are related to the conformations of the surfactant molecules. The observed temperature dependence of the quadrupole splittings is explained by changes of the conformational equilibrium.
