Recently, we demonstrated that a combination of product generation using meta-MD and barrier estimation + TS guess generation using the RMSD-PP method , both relying on semiempirical GFN2-xTB [17] calculations, could efficiently suggest the three lowest barrier elementary reactions of 3-hydroperoxypropanal. The results depend strongly on the parameters that control the biasing potential in the meta-MD and it is unclear how well this parameter set generalizes to other unimolecular reactants and to bimolecular reactions in general. Here we test the performance of this parameter set on elementary unimolecular reactions involving 163 reactant molecules and 20 elementary bimolecular reactions, both extracted from the recently published database of elementary reactions on two different DFT levels. In addition we test the method on two multi-step reactions related to organic synthesis.
