Force Field InformationThe Transferable Potentials for Phase Equilibria (TraPPE) force field were used to model carbon dioxide (CO 2 ) molecules [1], while the TraPPE-UA (United Atom) force field was used to model methanol (MeOH) molecules [2]. The parameters used in these two force fields for the Lennard-Jones 12-6 and Coulombic potentials are given in Table S1, harmonic potentials are given in Table S2, and the bond lengths are given Table S3 [1,2]. Table S1: Parameters for the Lennard-Jones 12-6 and Coulomb potentials for the TraPPE force field for CO 2 [1] and the TraPPE-UA force field for MeOH [2].
