We report a systematic study of inelastic light scattering for semidilute solutions of poly(adenilic acid). The results are analyzed in terms of a fast and a slow relaxation time. From their dependence on the wave vector and the polymer concentration, we are able to interpret the results in terms of a collective mode for the fast relaxation time at low wave vector, an individual chain motion for the fast time at large wave vector, and structural relaxation for the slow relaxation time.
