X-ray photodesorption yields in 10−2 molecules desorbed per absorbed photon of CH3CN, HCN, CH4, and CH3 from mixed 13CO:CH3CN and H2O:CH3CN ices irradiated at 15 K.
| Species | CO:CH3CN | H2O:CH3CN |
|---|---|---|
| CH3CN | 2.4 ± 1.2 | <0.5 |
| HCN | 4.5 ± 2.2 | 1.6 ± 0.8 |
| CH4 | <1 | 3.6 ± 1.8 |
| CH3 | 2.1 ± 1.0 | <1 |
Notes. These yields were derived from those displayed in Table 2 at 560 eV and assuming that up to 30 ML of the ice contribute to the desorption.
