Vacuum-Ultraviolet Absorption Spectra of Icy C2H4 at 13–60 K
Frontiers in Astronomy and Space Sciences, 2021 The thermal variation of absorption spectra of icy ethene in wavelength range 105–220 nm was measured from 13 to 100 K using a synchrotron as light source. Sublimation of icy ethene began above 62 K, resulting in decreasing absorption.
