Summary of effective yields of photon-triggered processes for investigated solid state species.
| Species | Photodesorption yield (mol.) | Photoconversion yield (mol.) | Relaxation (mol.) |
|---|---|---|---|
| CO | 20 | − | 80 |
| − | − | 100 | |
| CH4 | 160 | 20 | 80 |
| − | 20 | 80 | |
| CH3OH | < 0.04 | 50 | 50 |
| − | 50 | 50 | |
| CH3CN | < 0.3 | 50 | 50 |
| − | 50 | 50 |
Notes. Yields are given in molecules per 100 absorbed photons. First row for each molecule corresponds to processes in the active surface layers (3 ML), while the second row represents the ice bulk. The uncertainty for these values is estimated to be ±10%.
