Raman spectroscopy has been applied to the determination of molecular structural features in sulfonated polystyrene resins. Comparison with model compounds has facilitated the identification of key molecular vibrations which are characteristic of sulfonates and their undissociated acids. Of particular importance in the current study is the ability to undertake analysis of these resins in the hydrated state, with various amounts of water being present in the resins.
