According to eq 5, even if this violation were concentrated on a single atomic pair, it would correspond to an interatomic distance deviation of approximately √ 0.62δ(d) = 0.16d. Thus, this violation is sufficiently small, indicating that the obtained paths pass through or near the bottom of the FB-ENM. In other words, all obtained reaction paths preserve bond lengths, angles, and planar structures preserved in both reactant and product, while avoiding atomic collisions.
