    • The activation barrier corresponds to the energy difference between the T1-optimized geometry at r(Pt-Pt, 3.000 Å and the T1-local minimum geometry (1T1b) in 1 and between the T1-optimized geometry at r(Pt-Pt, 3.100 Å and the T1-local minimum geometry (2T1b) in 2, where the transition state is at r(Pt-Pt, 3.000 Å in 1 and at r(Pt-Pt, 3.100 Å in 2. These energy differences were calculated with the DFT(B3PW91)/basis-II//DFT(B3PW91)/basis-I method, where the geometries were optimized at each Pt-Pt distance. These activation barriers are a little bit overestimated, as follows: Because the transition state here is a crossing point of two states, the transition state should be calculated with a multireference method. However, the values presented here are not very much different from the correct values because the PEC of the T
    • 1 state is not steep but rather flat in the righthand side of the transition state (see Figure 4).
