A dividing-surface configuration near a free-energy or potential-energy saddle that controls reactive flux under a specified theory.

This is an authored directed relation from the source endpoint to the target endpoint.
A first-order saddle often approximates a transition structure, while dynamical recrossing and entropic coordinates can shift the kinetic bottleneck.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

This is an authored directed relation from the source endpoint to the target endpoint.
Activation energy is an apparent temperature-dependence parameter, whereas a transition-state free-energy barrier includes enthalpic and entropic contributions.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

Femtosecond spectroscopy directly resolved evolving wavepackets and transient structures near reaction bottlenecks in selected systems, without implying one universal classical path.
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.
