Time-resolved IR spectra from electron irradiation of CaCO3 at 50, 100, and 120 K under two electron fluxes, normalized to the preirradiation CaCO3 baseline and truncated to the 4.2–4.3 μm region to highlight the CO2 ν3 band. Vertical dashed lines mark the central wavelengths of the CO2 doublet, determined from double Gaussian fits to the continuum-removed spectra (gray). CO2 absorptions appear upon irradiation and gradually saturate. The strongest absorptions occur at 50 K under high flux. At higher temperatures, the absorptions are weaker, but radiolytic CO2 production is still apparent. -- astro-ph.EP
