Thermodynamic cycle illustrating the decomposition of the standard binding free energy [Eq. (13)]. Rsolv is the solvated receptor, Lsolv,C○ (upper left) is the ligand in solution at concentration C○, Lsolv,site (lower left) is the ligand solvated sequestered in the binding site, Lgas,site (lower right) is the ligand in the gas phase in a volume equal to the binding site volume, and RLsolv is the solvated complex.
