Ising model description of the dynamics

8 Distance-dependent relaxation near the core of the reverse micelle propagation of surface-induced frustration 

Confinement brings novel features into the dynamics of water in reverse micelles. Markedly non-exponential deeay exists due to two different behaviors, near the surfaee and inside the pool, at least for intermediate to large reverse micelles (Wo 4). For larger sizes, relaxation changes from the slow behavior near the surfaee to the fast relaxation at the pool [5]. 

In the case of reverse micelles there is no conclusive signature of such an effect. Computer simulation, however, does indeed show an initial relaxation of water that is faster than in the bulk. 

Water in and around micelles, reverse micelles, and microemulsions 

Water in eonfined systems (discussed here and also in the next chapter) exhibits features markedly different from those observed in bulk water. While such studies are important in their own right, they also are relevant for biological systems where water molecules are always restricted and/or confined. Reverse micelles in particular provide a good model to study the effects of such confinement.
