Free energy surfaces for the PCET reaction in a rhenium-tyrosine complex.88 In the center frame are slices of the free energy surfaces along a collective solvent coordinate. In the left frame is the reactant (I) proton potential energy curve and the corresponding proton vibrational wavefunctions along the proton coordinate evaluated at the minimum of the ground state reactant free energy surface. In the right frame is the product (II) proton potential energy curve and the corresponding proton vibrational wavefunctions along the proton coordinate evaluated at the minimum of the ground state product free energy surface.
