We examined the interaction between a single TBT molecule and one LiTFSI salt pair under three different dielectric constants, ϵ = 10.6, 8.0, and 6.0. The correction term, C ij 4 , is Table : Calculated binding free energies (∆F (r min )) in kcal/mol and their corresponding distances (r min ) in Å for systems TBT (I i ) and 2 TBTs (II i ) in implicit solvent, under three different dielectric constants: ϵ = 10.6 (a), ϵ = 8.0 (b), and ϵ = 6.0 (c).
