Electron affinity determinations
| EA (eV) | Method | Reference | Comment |
|---|---|---|---|
| 1.60 ± 0.50 | EIAE | Thynne, 1972 | From PF2NCS. G3MP2B3 calculations indicate an EA of ca. 0.75 eV.; B |
| 1.50 ± 0.50 | N/A | Chase Jr., Curnutt, et al., 1982 | Computations indicate EA ca. 17 kcal/mol; B |
| >1.60 ± 0.50 | SI | Page and Goode, 1969 | The Magnetron method, lacking mass analysis, is not considered reliable.; B |
