Electron affinity determinations
| EA (eV) | Method | Reference | Comment |
|---|---|---|---|
| <3. | LPES | Wren, Vogelhuber, et al., 2009 | Schwartz, Davico, et al., 1999 really HCI2-. Upper limit only determined here, and true value may be appreciably less. Hajgato, Nguyen, et al., 2000 caln: s<t by ~7 kcal |
| 2.090 ± 0.070 | LPES | Schwartz, Davico, et al., 1999 | Singlet 1±3 kcal/mol up from triplet. Calculations ( Hajgato, Nguyen, et al., 2000) say singlet 7 kcal<triplet |
