    • Also note that this barrier is not centered at s = 0.5 due to the computation of s in eq 1 using the mean square displacement,41 which is not a linear function of ω: The NMA structure with an ω value of opposite sign to R(4)'s is located at s = 0.41, not s = 0.50.

    • First, because the reference path is not optimized, the minimum of the potential energy could be displaced from z = 0. Second, even if the potential energy term is minimum at z = 0, the number of accessible configurations (and thus the entropy) increases with z, yielding a negative free energy gradient with respect to z. The balance between these two effects is not trivial and can lead to a displacement of the free energy minimum along z.
