Early Earth gas tholin sample produced from nitrogen:methane:carbon dioxide (N₂:CH₄:CO₂ with a 99.8:0.1:0.1 ratio) gas precursors by UV photolysis at 297 K temperature and 630 Torr pressure at University of Colorado, Boulder, CO, USA.
Tholin sample produced as spherical particles with sizes ranging from 20 to 400 nm.
The real (n) and imaginary (k) parts of the complex index of refraction were determined from optical measurements done at a temperature of 297 K and a pressure of 630 Torr, by cavity ringdown aerosol extinction spectroscopy at λ = 532 nm.
Error bars/uncertainties are provided in the downloadable data.
