Uranus and Neptune gas tholin sample produced from methane:hydrogen (CH₄:H₂ with a 0.07:0.93 ratio) gas precursors by RF plasma discharge at 300 K temperature and 0.13 mbar pressure at Laboratory for Planetary Studies, Cornell University, Ithaca, NY, USA.
Tholin sample deposited on glass (SiO₂) and cesium iodide (CsI) substrates. Film thickness of 6.6 μm at measurement location.
The real (n) and imaginary (k) parts of the complex index of refraction were determined from optical measurements done at room temperature, by a combination of ellipsometry and transmission techniques from 0.4 to 1.0 µm.
For the bright areas of the sample, n = 1.56 ± 0.05, for the dark areas, n = 1.56 ± 0.05.
