Description
NIR reflectance spectra of AMES tholins (from 90% N2:10% CH4) pure and mixed with different liquids and solids (CH4, C2H6 and CH3CN+C2N6) at temperatures from ambient to 88 K. Spectra were recorded upon cooling while the liquid was progressively added. Freezing occured at some point.
Number of spectra
24
Variable type(s)
  • sample composition
  • sample abundance
  • temperature
Comments
Sample abundance is varying with time during liquid addition and its sublimation.
