The structure and conductivity of AOT (sodium bis(2‐ethylhexyl) sulfosuccinate) solutions (2.5 × 10⁻⁴–2.5 × 10⁻¹ M) in n‐hexadecane‐chloroform mixture at the chloroform concentration from 50 to 100 vol% were studied. The diffusion ordered spectroscopy NMR study revealed that in the indicated range, the observed hydrodynamic diameter of micelles depends only on the AOT concentration and does not depend on the chloroform content. Molar fractions of free AOT molecules and those aggregated into micelles were calculated using the Lindman's law: at concentrations above 2.5 × 10⁻¹ М, the solutions contain mostly the micelles, whereas at concentrations below 2.5 × 10⁻⁴ M, the solutions contain AOT molecules. The transition region contains both the AOT molecules and the micelles. Conductivity measurements were used to determine free charge carriers in the bulk of solutions and their contributions to conductivity.

正十六烷-氯仿混合物中AOT溶液的结构和电导率。

研究了AOT（双（2-乙基己基）磺基琥珀酸钠）（2.5×10 ^-4 –2.5×10 ^-1 M）在正十六烷-氯仿混合物中的氯仿浓度为50至100体积％的溶液的结构和电导率。扩散有序光谱NMR研究表明，在指定的范围内，观察到的胶束流体动力学直径仅取决于AOT浓度，而不取决于氯仿含量。自由AOT分子的摩尔分数以及那些聚集成胶束使用Lindman定律计算：浓度超过2.5×10 ^-1 М，溶液主要包含胶束，而在低于2.5×10浓度^-4M，溶液中含有AOT分子。过渡区同时包含AOT分子和胶束。电导率测量用于确定大部分溶液中的自由电荷载流子及其对电导率的影响。
