In addition, the AMC-xTB model achieves a more narrow error distribution with the root mean square deviations decreasing from 7.6-12.3 kcal/mol to 0.81-1.45 kcal/mol, implying that there will be fewer outliers. The error span on the larger clusters for the Knattrup et al. and Kubečka et al. sets are similar to the error span for the smaller clusters in the optimization set. This shows that reparameterizing on smaller clusters is adequate for calculations on larger-sized clusters as the model gets some of the underlying chemistry correct and scales effectively with system size. α is the Bohr radius. The Clusteromics set is (SA/FA/MSA/NA) 0-2 (AM/MA/DMA/TMA/EDA) 0-2 clusters, the Kubečka et al. set is sulfuric acid-multi-base (SA) 1-4 (AM/MA/DMA/TMA/EDA) 1-4 clusters, Knattrup et al. is the multi-acid-muti-base (SA/FA/MSA/NA) 1-4 (MA/DMA/TMA) 1-4 clusters including the new AM-containing clusters sampled in this work.. The structures are equilibrium structures at the ωB97X-D/6-31++G(d,p) level of theory.
