The passage of the system from one PES to the other (see Figure 28) corresponds, simultaneously, to switching of the localized electronic state and tunneling of the proton between vibrational states localized in the two PESs.
Two PESs for t-SO were also optimized at the BP86/6-31G(d)/CHARMM22 and BHandHLYP/6-31G(d)/CHARMM22 levelsof theory, to test the dependence of the barriers on the density functional.
The minimum value of the barrier on the crossing seam of the two PESs is a saddle point for the lower adiabatic PES, which is essentially identical to one of the diabatic states around each minimum.
Finally, Δ E is the energy difference between the minima of two PESs as in Figure 18a, with the value 9.10Here, εB(R̅B, Q̅B) and εA(Q̅B) are the energies of the solvated molecule BH and ion A–, respectively, at the final equilibrium geometry of the proton and solvent, and εA(R̅A, Q̅A) and εB(Q̅A) are the respective quantities for AH and B–.
To confirm the mechanism and obtain more accurate reaction energetics and transition state structures, two reaction path optimizations were performed at the density functional theory (DFT) (B3LYP/6-31+G B3LYP/6-31+G QM/MM level, using starting conformations from two PESs with the Tyr137-Ser47-Tyr110′ hydrogen bond network in place.
