Chemical | Softness (σ, ×10−3eV−1) | Electrophilicity (ω, eV) |
---|---|---|
Carbon disulfide | 359 | 3.97 |
Methyl acrylate | 315 | 3.22 |
Acrylamide | 315 | 2.62 |
2,5-Hexanedione | 310 | 2.09 |
n-Propyl bromide | 270 | 1.93 |
Vinyl chloride | 277 | 1.71 |
For each compound, respective orbital energies (ELUMO, EHOMO) were obtained from ground state equilibrium geometries with DF B3LYP-6-31G* in vacuum from 6-31G* initial geometries and were used to calculate softness (σ) and the electrophilic index (ω) as described in LoPachin et al. [35].
