Naturally, delocalization from the C-C double bond, which is determined by evaluating the sum of the |CT/CG| values from pC@C and rC-C orbitals, is maximized at the optimized TS. Note that the maximal value for |CT/CG| from
rCAC/gem to Cl+ is at a dihedral angle of 105, while delocalization from rCAH/vic to Cl+ is at 90, where pC-C and rCAH/vic are almost parallel. However, the TS is not located at these points. Both delocalizations should be effective in the TS.
