用二维NOE光谱（NOESY）研究了正丁醇和苯在阴离子十二烷基硫酸钠（SDS）胶束中的溶解以及苯在阳离子十二烷基三甲铵（DTAB）胶束中的溶解。在所有情况下，获得显著的正NOESY交叉峰，其似乎与这些表面活性剂体系中这些增溶物的增溶的预期位点良好相关。NOESY技术，这是一种非侵入性的实验，被发现提供显着的洞察力方面的溶解这些分子在内部的离子胶束。
Two-dimensional NOE spectroscopy (NOESY) experiments have been used to examine the dissolution of two typical solubilizates (1-butanol and benzene) in anionic sodium dodecyl sulfate (SDS) micelles and of benzene in cationic dodecyltrimethyammonium (DTAB) micelles. In all cases, significant, positive NOESY cross peaks were obtained that appeared to correlate well with the expected locus of solubilization of these solubilizates in these surfactant systems. The NOESY technique, which is a noninvasive experiment, is found to provide significant insight in terms of the solubilization of these molecules in the interior of ionic micelles.
