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.
Variable(s)
sample composition, sample abundance, temperature
Variable comments
Sample abundance is varying with time during liquid addition and its sublimation.
