Proton affinity at 298K
| Proton affinity (kcal/mol) | Reference | Comment |
|---|---|---|
| 157.1 | Spanel, Smith, et al., 1995 | T = 300K; GB > acetylene, < CS2, H2O; PA assigned based on DS (B - BH+) = 10.0 cal/mol K based on Hunter and Lias, 1998, but assignment of DS not clear Temperature dependent equilibrium study and ab initio calculation would be useful |
