Figure 2:
AMOEBA+ and QM interaction energies for Li, Na, K, Rb, and Cs. QM total interaction energy is calculated by CCSD(T)/CBS, while energy components are calculated by SAPT2+. “Elst” denotes electrostatics; “Ind” denotes induction, which is the total induction energy in SAPT or the sum of polarization and charge transfer energy in AMOEBA+. For ion-water dimer and homodimer, QM energy is represented as solid lines and MM energy is represented as hollow symbols.
