| Gas phase | CH3F | F- | TS | |||
| Energy(hartree) | -139.41718 | -99.66595 | -239.08651 | ΔEnergy(kcal/mol) | -2.1 | |
| Microsolvation | CH3F | F-_H2O | TS | |||
| Energy(hartree) | -139.41718 | -175.96960 | -315.37293 | ΔEnergy(kcal/mol) | 8.7 | |
| Continuum model | CH3F | F- | TS | |||
| Energy(hartree) | -139.42076 | -99.79904 | -239.18795 | ΔEnergy(kcal/mol) | 20.0 |
Conclusion : The solvation effect has rasied barrier height, that cause reaction hard to react
