Nous présentons ici des mesures spectrales de la lumière dépolarisée diffusée par un mélange binaire (nitrobenzène et n-hexane) près de son point critique de démixion. La lumière diffusée dépolarisée est due principalement aux fluctuations d'orientation et aux rediffusions multiples. Un Fabry-Pérot de 60 GHz d'intervalle spectral libre permet de séparer spectralement ces deux contributions. La largeur de la raie de réorientation se comporte comme la viscosité. Suffisamment loin du point critique, la variation spatiale et la dépendance en température de l'intensité de diffusion multiple sont bien expliquées par un calcul invoquant un processus de double diffusion, en bon accord avec la récente théorie d'Oxtoby et Gelbart, à condition de pren...
