Abstract

The alkyl chain conformations of the surfactants Na-dodeca-noate (I) and Na 10-undecenoate (II) have been analyzed in various phases by monitoring the diagnostic Raman bands. While I adopts the all-trans chain conformation in the crystalline state, chain kinking is seen when it is dissolved in water, particularly above its critical micelle concentration. The terminally functionalized surfactant II has an all-trans chain geometry in the solid state and at premicellar concentrations in water. The alkyl chain in II adopts gauche conformation beyond micellar concentrations in water. II also adsorbs in the bent mode to colloidal silver particles in water, using both the carboxylate and the chain terminal olefinic moieties as attaching ligands to the metal surface.
