Electron affinity determinations
| EA (eV) | Method | Reference | Comment |
|---|---|---|---|
| 1.149 ± 0.087 | IMRE | Mishima, Huh, et al., 1995 | ΔGea(343 K)=-27.1 kcal/mol. Reanchored to EA(PhNO2), Kebarle and Chowdhury, 1987. |
| 1.123 ± 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. |
