To validate this model with an external test set, the decomposition temperatures of our set of 12 non-symmetric ditetrazoles were predicted. The ditetrazoles were parameterized in the same fashion as the training set using structures generated from conformational searches and subsequent DFT computations. As before, the lower predicted value between the two tetrazole moieties was adopted as the predicted property for the HEM in accordance with the trigger hypothesis. This resulted in good predictions for the decomposition temperature for 9 of the 12 ditetrazoles, giving a MAE of 16 °C. The total MAE for all 12 ditetrazoles was 31 °C.
