To further validate the accuracy of the energetic properties of the CG models and their transferability, we conducted two categories of tests. In the first test, we calculated the solvation free energies G for six alkane molecules including BUT, PET, HEX, OCT, CHP, and COC in both BEN and CHE solvents. Figure presents a comparative chart of the solvation free energies for the CG and AA systems, including 12 molecules in total. The absolute deviations between the solvation free energies of the CG and AA systems were maintained within 3.0 kJ/mol, with a MAD value of 1.5 kJ/mol.
