Mechanisms
The key energetic quantities are labelled as follows:
Mechanism 1:
V (R) is the reactant’s potential energy.
ΔV Δ (I ) is the well depth for the fi rst intermediate.
1
ΔV Δ (TS ) is the net activation barrier for the forward reaction.
1
ΔV Δ A VA V is the intrinsic activation barrier for the forward reaction.
ΔV Δ (I ) is the well depth for the second intermediate.
2
ΔV° Δ is the forward reaction energy.
Mechanism 2:
V (R) is the reactant’s potential energy.
ΔV Δ (TS ) (= ΔV Δ 1 A VA V ) is the net and intrinsic activation barrier involving
