For the out-of-plane bending, shown in Figure , there is also a change in mechanism for strong enough many-body potentials. Surprisingly, this deformation opens up a different alternate reaction path: nitro group scission, which is higher in activation energy than both the intra-and inter-molecular H-transfer reactions , and does not activate the inter-molecular H transfer at all. The availability of the new path coincides with a conformation change in the TATB. As described in detail in Section S8 of the SI, the inner C ring buckles and the nitro and amino groups may more freely rotate. This structural change causes the change in slope of activation energy vs. deformation shown in Figure and Section S7 of the SI. The inset in Figure shows instances of an intramolecular h-transfer (bottom arrow) and a nitro scission (top arrow). Hence, we find that not only does deforming a different DoF in the system result in different levels of activation barrier reduction, but it also opens different pathways for decomposition reactions to take place.
