Résumé

The different numerical models that have been developed to explain the characteristics and properties of the Titan's haze require knowledge of optical constants of Titan's aerosols. Here, we present the optical constant characterization of Titan aerosol analogues or "tholins" produced with the PAMPRE experiment. Tholins have been produced in different N2-CH4 gaseous mixtures to discuss the effect of the initial methane concentration on the optical constants. The real (n) and imaginary (k) parts of the complex refractive index have been determined using the spectroscopic ellipsometry technique.
