Depiction of the reaction network of the C₂H₄ + CH₂CCH⁺ reaction. The energies are calculated at the DLPNO-CCSD(T)/aug-cc-pvtz level with the ωB97XD/def2-TZVPD harmonic ZPE. In the diagram, EQ ‘equilibrium structure’ refers to the wells (local minima) on the PES; TS stands for ‘transition states’ and DC ‘dissociation channels’. This nomenclature is chosen to be consistent with that provided by the GRRM code (Maeda et al. 2023b).
