Table 3.
Product branching ratios for each irradiation source in both the condensed and gas phase for the CH3CN parent.
| CH3CN | Condensed phase | Gas phase | ||
|---|---|---|---|---|
| Species | VUV | Electrons | VUV | Electrons |
| HCN | 1 | 1 | 1 | 1 |
| CH3NC | 0.6 (0.1) | 0.7 (0.1) | 0.8 (0.1) | 0.5 (0.1) |
| CH3CH2CN | OL | OL | 1.0 (0.1) | 0.3 (0.0) |
| CH2CNCH | 0.9 (0.1) | 4.0 (0.4) | LOD | LOD |
| CH4 | 1.7 (0.4) | 1.0 (0.2) | ND | ND |
Notes. OL – Overlap of band in the RAIRS spectrum. LOD – Outside the limit of detection based on transition strength and number of molecules formed. ND – No permanent dipole moment preventing millimeter-wave detection.
