1H-NMR spectra of Aerosol-OT (AOT) reverse micelles in isooctane are reported at various water contents and several temperatures. The resonances from the AOT protons near the polar head are completely assigned. The NMR parameters (chemical shift and linewidth) appear to be suitable probes for characterizing the physico-chemical state of micelles, in particular in order to define the range in which the system is fully homogeneous and transparent. The results correlate well with those obtained from optical density measurements. Lanthanide ions dissolved in the water phase selectively perturb the AOT resonances from the protons nearest to the polar head; conversely, non-polar shift reagents soluble in the organic phase do not cause appreciable effects on any of the observable signals.
本文报道了在不同含水量和几个温度下，异辛烷中气溶胶-OT（AOT）反胶束的1H-NMR谱。极性头部附近AOT质子的共振峰已完全归属。NMR参数（化学位移和线宽）似乎是表征胶束物理化学状态的合适探针，特别是为了确定体系完全均匀和透明的范围。结果与通过光密度测量得到的结果很好地相关。溶解在水相中的镧系离子选择性地扰动了离极性头部最近的质子的AOT共振；相反，溶解在有机相中的非极性位移试剂对任何可观测信号都没有明显影响。
