Micelles and reverse micelles have been studied for a long time using small angle scattering techniques. Information extracted from such studies might typically be in the form of radii of gyration, the degree of dispersion in such radii, the thickness of the surfactant shell, and the degree of penetration of the oil into the surfactant tail. Interest in these materials is however on-going right up to the present time because of their relevance to broad range of fundamental phenomena, such as the atom scale structure and dynamics of water in a high degree of confinement, as well as having many chemical and biochemical applications. Reverse micelles are particularly relevant in this context because in these systems it is the water that is confined. In this study we will for the first time develop an atomistic model of a reverse micelle based on scattering data from NIMROD.
