Abstract
Rayleigh-Brillouin scattering spectra (RBS) in molecular Oxygen have been simulated by DSMC. Different scattering models have been implemented based either on the Larsen-Borgnakke relaxation model and on the Classical Trajectories technique. Results are compared with recent experimentally measured spectra showing good agreement. It is suggested that DSMC-based models be used in the interpretation of light scattering experiments in place of the simplified kinetic models, widely used for the interpretation of RBS experiments. Actually, the former have a firmer physical ground and are readily extended to treat gas mixtures of arbitrary complexity.
