Table 2.
Summary of parameters that impact the efficiency of the kick-out photodesorption mechanism.
| Species | Intermol. bond energy (eV) | Diss. threshold energy (eV) | Energy trans. to a surface species (eV) | Ratio |
|---|---|---|---|---|
| CH4 | 0.1 | 4.5 | < 0.99 | 9.9 |
| CH3OH | 0.38 | 4.5 | < 0.58 | 1.5 |
| CH3CN | 0.39 | 4 | < 0.46 | 1.2 |
Notes. The last column is the ratio of the upper limit for energy transferred to surface species to the intermolecular bond energy (see text below for details).
