Paper Abstract

Surfactant monolayers are formed by the adsorption of dodecane sulfonate sodium salt from bulk aqueous solutions to the air-water interface. The reflection-absorption of polarized infrared radiation from the surface is probed with respect to the bulk concentration of the water soluble surfactant and the concentration of sodium chloride in the subphase. The anisotropic orientation of the amphiphiles is calculated by using optical modeling equations. Inferences about the conformation of the alkyl chain are made from frequency information.
