Parameters and cross section for band-formation process.

Formamide adsorbed by pyrite
Peak (cm−1) Mode α (min−1) R2 σf (cm2)
2341 νas CO2 0.043 ± 0.011 0.8 (3 ± 1) × 10−20
Formamide adsorbed by forsterite
Peak (cm−1) Mode α (min−1) R2 σf (cm2)

2340 νas CO2 0.0121 ± 0.0016 0.94 (0.8 ± 0.2) × 10−20

Notes. First column: bands that increased in intensity during the irradiation experiment; second column: vibrational modes; third column: the formation rate α obtained through the Eq. (4); fourth column: R2 points to the goodness of fit with which α was obtained; fifth column: formation cross section evaluated through Eq. (5).
