Titan gas tholin sample produced from nitrogen:methane:hydrogen:acetylene:ethylene:cyanoacetylene (N₂:CH₄:H₂:C₂H₂:C₂H₄:HC₃N with a 0.98:0.018:0.002:3.5E-4:3.0E-4:1.7E-5 ratio) gas precursors by UV photolysis at 297 K temperature and ~700 Torr pressure at Rensselaer Polytechnic Institute, Troy, NY, USA.
Tholin sample deposited on quartz (SiO₂) substrate. Film thickness of 40-60 nm.
The real (n) and imaginary (k) parts of the complex index of refraction were determined from optical measurements done at room temperature, by reflection and transmission spectroscopy from 0.2 to 2.5 µm.
The accuracy of k is estimated at ± 10% at 0.4 µm and ± 75% at 0.8 µm.
