Title: Near infrared spectra of potential solids at the surface of Titan
Abstract: The laboratory measurement of the optical properties in the near infrared (1 to 5 micrometers) of solid CH4, C2H6, and C2H4 and some of their mixtures is reported and results are given. With these data the spectra of three mixtures at a resolution comparable to the one of the near infrared spectrometer of the instrument of the Huygens probe were simulated. It was found that at the Descent Imager/Spectral Radiometer's (DISR's) resolution the best features to probe the composition of solid surface on Titan are near 6000, 7500, and 8600/cm for methane, near 7900, 7200, and 8400/cm for ethane and near 6100/cm for ethylene. In some cases concentrations lower than a few percent may be derived from the analysis of the complete infrared spectrum.
