Water is a polar molecule that participates in hydrogen bonding and proton transfer. Geometric confinement and water’s interactions with osmolytes (small water soluble compounds) affect the ability of water molecules to hydrogen bond and transfer charges. Study of this behaviour of water with different osmolytes in controlled environments will help us develop predictive models. In our study, we have prepared Sodium bis(2-ethylhexyl)sulfosuccinate (AOT) reverse micelles (RM) in 2,2,4-Trimethylpentane (Isooctane). Our principle osmolytes were the straight chain sugar alcohols glycerol and erythritol. Study of water-osmolyte behaviour in the small and confined pool of a reverse micelle allows us examine the difference in water-osmolyte interaction in nanoscopic solution as compared to bulk solution. Additionally, we also aim to explore the effects of glycerol and erythritol in the stability of AOT reverse micelles.
