Electron affinity determinations
| EA (eV) | Method | Reference | Comment |
|---|---|---|---|
| 1.43 ± 0.10 | IMRE | Mishima, Kang, et al., 1993 | ΔGea(343 K) = -32.3 kcal/mol; ΔSea (est) = -2.0 eu. |
| 1.383 ± 0.087 | IMRE | Huh, Kang, et al., 1999 | ΔG(EA) 343K; anchored to ΔG value. Including anchor ΔS, EA is ca. 0.4 kcal/mol more bound. |
