## Abstract We have compared four theoretical effects of rodlike macromolecules with the fast components, i.e., components other than translational diffusion, of our experimental data, which are presented as amplitude autocorrelation functions of electric field scattered from dilute solutions of mo

Abstract
The authors describe small‐angle neutron scattering measurements of the screening length ζ in polyacrylamide‐water gels. Although these are inhomogeneous systems, the screening length is clearly observable and is in good numerical agreement with the relation E = 3__kT__/4πζ^3^, where E is the longitudinal elastic modulus of the gel obtained from measurements of the intensity of qu‐asielastically scattered light. Static light scattering observations reveal a larger‐scale (ca. 30 nm) superstructure in the gel.

Comparison between low frequency Raman scattering and inelastic neutron scattering of amorphous polybutadiene shows that the light-vibration coupling coefficient is linearly frequency dependent. This agrees with earlier findings and we show here that it can be interpreted employing two different cor
