Abstract
Multiple-beam interferometry is used to determine the refractive index profile of the aqueous medium as a function of the separation between two Molecularly smooth mica surfaces rendered hydrophobic by surfacta nt adsorption from bulk solution. Within experimental accuracy, no dev iation from the bulk value is found. The consequences of this observat ion are discussed in view of recent proposals as to the origin of the hydrophobic attraction.
