对气溶胶OT-水体系(从气溶胶OT的10%到70%)中液晶片层相的X射线衍射研究表明，结构的基本重复距离随水含量的变化接近于一维膨胀的预期。气溶胶OT的含量很低，其对结构参数计算结果的影响几乎可以忽略不计，这一结论与以前的一些推论相反。在气溶胶OT的中间区域(从气溶胶OT的34%到42%)，存在一个两亲层和水层内的分子排列可能发生重组的范围。然而，这一现象的性质仍不得而知。
A renewed X-ray diffraction study of the liquid crystalline lamellar phase occurring in the Aerosol OT—water system (from 10 to 70% of Aerosol OT) has disclosed that the variation in the fundamental repeat distance of the structure with the water content is close to that expected for a one-dimensional swelling. The content of Aerosol OT in the intervening water layers between the amphiphilic lamellae is so low that its influence on the results of a calculation of the structural parameters is almost negligible, a conclusion which is in contrast to some earlier inferences.In the middle of the lamellar mesophase region (from 34 to 42% of Aerosol OT), there is a range where the molecular arrangement inside the amphiphilic and aqueous layers may undergo a reorganization. The nature of this remains, however, unknown.
