Entropy values are given for Shg the host-guest complex, Sg(complex) the guest only in complex, Sh(complex) the host only in complex, and Sg(solution) the guest in solution. Shg, Sg(complex), Sh(complex), and Sh(solution) are computed from 5ns simulations while Sg(solution) values are computed from 1ns simulations. All entropy values (except where marked) in cal/mol/K. ΔSconf = Shg – Sh(solution) - Sg(solution). TΔSconf computed at 300K, with units of kcal/mol.
