© 2018 American Chemical Society. The result of the application of different approaches based on the ideal gas/rigid rotor/harmonic oscillator (IGRRHO) model, commonly used in popular software packages, for the calculation of free energies in solution is compared with that of ab initio molecular dynamics for a process involving ligand exchange in palladium complexes. The IGRRHO-based approaches considered differ in most cases in the extent to which the rotational and translational contributions are included in the correction. Our study supports the use the free energy values directly obtained from dispersion-corrected DFT functionals without any correction or with minor corrections at most.
