Large deviations from the Clausius-Mossotti equation in a model microemulsion

Abstract
We report experimental measurements of the Kerr coefficient in a model three-component microemulsion. Our measurements show that domains of the dispersed phase are strongly correlated, even for moderate to low concentrations of the dispersed phase. Such a correlation invalidates the use of the Clausius-Mossotti equation, which has been a common practice in the interpretation of light-scattering and birefringence data.
