Figure 10.
Distribution of O*-O distance, where O is the closest atom not hydrogen bonded to O* in the (A) protonated LS2 channel and (B) CNT. The noticeable peak before 2.8 Å produced by SCC-DFTB indicates that on average some first solvation shell water molecules are not hydrogen bonded to the hydronium, which perturbs the “special pair dance” dynamics in the resting state of PT (see main text).
