Fig. 1: A complete schematic potential energy diagram for the stationary configurations on the minimum-energy paths of the Cl + C2H2 reaction.
From: Exclusive roaming mechanism for the Cl + C2H2→C2H + HCl bimolecular reaction
The label energies are calculated relative to the fragment Cl + C2H2 (with vibrational zero-point energies). The energy shown in parentheses is from UCCSD(T)-F12a/AVTZ calculations, and the unit of energies is kcal/mol.
