Comparing ion-paired ΔEi values in fluorobenzene (Table ) with non-ion-paired values (Table ) reveals significant ion-pairing effects. For sheets with n = 6-8, the ion-pairing contribution ranges from 54 to 58 kJ mol -1 , yielding and average value of 55.7± 1.9 kJ mol -1 . However, this consistency does not extend across the full range of MAO sizes.
