The relative free energy difference (AAGhyd) for the reversible addition of water to two unsaturated molecules is accurately computed using a combination of ab initio quantum mechanical calculations and free energy perturbation methods. Initial attempts to calculate the absolute hydration free energ
## Abstract This study describes the framework of the quantum mechanical (QM)/Monte Carlo (MC)/freeโenergy perturbation (FEP) method, a FEP method based on MC simulations using quantum chemical calculations. Because a series of structures generated by interpolating internal coordinates between tran
