=== Spectroscopic instruments and techniques ===

The spectra of basalts were collected using the ASD FieldSpec® 3 spectrometer in the spectral range of 0.35-2.5 μm, with 3 nm spectral resolution in the visible range and 10 nm in the infrared (instrument of Laboratoire de Planétologie et Géodynamique Nantes).

The spectra of tholins were collected using a Fourier Transform Infrared spectrometer (Nicolet, model NEXUS 670) configured with a drift reflectance accessory (Harrick, model Praying Mantis DRP) mounted inside the instrument compartment (instrument of NASA Ames Research Center).


=== Systems and cells ===

The tholin experiments were conducted in the Andromeda chamber (Wasiak et al. 2013) at the Keck Laboratory of the Arkansas Center for Space and Planetary Sciences.
