The Raman spectra were measured for sodium alkyl sulfates and potassium aliphatic carboxylates in the solid state and aqueous solutions. Vibrational assignments of Raman lines were made, and characteristic Raman lines of the alkyl sulfate ion were identified. The ethyl sulfate ion in the aqueous solution was found to exist predominantly as the <I>trans</I> form about the CH<SUB>2</SUB>–O bond. For higher alkyl sulfate ions in aqueous solutions, Raman lines due to rotational isomers with <I>gauche</I> CH<SUB>2</SUB>–CH<SUB>2</SUB> bonds were observed. Longitudinal accordion frequencies of the solid state and aqueous solutions were compared in order to discuss the conformations of hydrocarbon chains in solution.
