L'analyse de la diffusion Rayleigh-Brillouin dans les gaz dilués nécessite un traitement à l'échelle moléculaire quand les longueurs d'onde des fluctuations observées deviennent comparables au libre parcours moyen. On peut formuler un problème de valeurs initiales fondé sur l'équation de Boltzmann linéarisée pour calculer les fonctions de corrélation de la densité quel que soit le rapport de la longueur d'onde au libre parcours moyen. Dans cette communication cette manière d'aborder le problème est appliquée aux mélanges binaires de gaz. La présence de différents modes de fluctuation de la densité entraîne des variations intéressantes du spectre de la lumière diffusée en fonction de la densité et de la polarisabilité de chaque espèce.
