Average minimum in the D–A distance in the neighborhood of the reaction.
CMD applied to the transferring hydride.
CMD applied to the transferring hydride and the secondary hydrogen, which rehybridize during the reaction.
CMD applied to the transferring deuteride, which replaced the hydride as the transferring particle.
