Workflow: Explosophores are the key reactive moieties responsible for the initiation of HEM deflagration and detonation. The viability of our explosophore-based approach to sensitivity prediction was initially explored using subsets of our larger dataset featuring HEMs containing only a single explosophore. Our workflow proceeds by first identifying an explosophore family of interest, followed by interrogation of a sensitivity property for prediction (Tdec or log(IS)). This selection process typically yielded datasets of 30-50 compounds suitable for MLR modeling. Of the HEMs in a selected explosophore class, compounds with multiple, nonequivalent instances of the explosophore are treated separately (vide infra). Once a dataset was curated, we then parameterized each molecule using our ensemble of chemical descriptors.
