摘要：

We present a model based on effective pair interactions to describe the arrangement of sodium polystyrene sulfonate chains in suspension. The potential functions are obtained from the analysis of all-atom simulations and they are the main ingredient of a Brownian dynamics simulation. The resulting configurations are used to reconstruct the corresponding scattering intensity spectra that have the main features of experimental patterns. This coarse-grained model in conjunction with the reconstruction scheme allows us to gain some insights on the structural properties of a polyelectrolyte in solution. [GRAPHICS] .
