For 1, we have selected four temperatures from the 600 - 1250 K range, whereas for 2, five values have been chosen from the 800 - 1800 K temperature range to calculate the temperature dependence of the activation free energy. The minimum size of the intervals is 200 K, which is sufficiently large to observe the effect of the temperature.

We have calculated the NICS in the point obtained by shifting the center of mass of the six carbon atoms participating in the Cope reactions perpendicularly to their least-square plane by 0.5 A outward from both molecules 1 and 2. 0 K calculations showed that the variation of the NICS in this point nicely reflects the formation of the TS aromaticity. See the Supporting Information for further details
