    • Note that the transmission coefficient κ is not only a tunneling correction but also takes into account three effects: tunneling, which tends to make κ > 1, nonclassical reflection of trajectories that classically would overcome the barrier, which tends to make κ < 1; and a better treatment of the reaction threshold than the canonical variational transition state theory, which also makes κ < 1. The net effect in the abstraction reaction is κ > 1, while in the addition reaction it is κ < 1. For a detailed description of the calculation of transmission coefficients and threshold corrections see ref 39
