Fig. 5

MIR (2220−690 cm−1) FT-IR spectra of CO2:H2O (6:1) ice mixtures deposited at 20 and 80 K before (solid gray at 20 K and black lines at 80 K) and after (solid blue at 20 K and red lines at 80 K) 1 keV electron irradiation with a total fluence of 2.2 × 1017 e− cm−2. The inset shows the difference spectra of the CO2:H2O (6:1) ice at 20 K after and before electron exposure.
