The computer simulation technique of Langevin dynamics is used to simulate the growth of smoke agglomerates. Clusters consisting of between 10 and 700 primary particles are generated, and the light scattering from these clusters is calculated in the Rayleigh-Debye limit. The results of these calculations are then used to illustrate how light-scattering measurements can be used to infer the concentration, the size, radius of gyration, and the fractal dimension of the agglomertes. The pair distribution function for these agglomerates is shown to be a scaled function of r/R "nedsänkt" till g.
