The purpose is to follow a structural evolution as water soluble (normal curvature) micelles are gradually transformed into oil soluble (reversed curvature) aggregates. Although much is known about the two separate extremes (normal and reversed), the transitional states present in solvents of intermediate polarity are less well studied. Three solvents will be employed: water, dioxane and cyclohexane. Owing to mutual miscibility (water/dioxane and dioxane/cyclohexane) it is possible to continuously vary the solvent properties from high to low polarity. Two surfactants (AOT and C12E5) will be used; both form micelles in aqueous and apolar media. Therefore, the inversion from normal to reversed micelles will be achieved by continually varying the solvent quality (composition) by controlled solvent blending.
