			- QM data were generated describing the single and
			(if relevant) double and triple bond dissociation
			for all B/N/O/H combinations. These data were used
			to derive initial ReaxFF bond parameters, and all
			calculations were performed using DFT with the B3LYP
			functional and the Pople 6-311G** basis set.

			- The training set was then extended with QM data
			describing angular distortions in a set of small
			AB-related (AB = H3N-BH3) molecules. These data
			were used to derive the initial ReaxFF angular
			parameters.

			- The training set was extended with reaction barriers
			for key reaction steps such as H2 release
			from AB, dimerization of H2B-NH2 and reaction
			energies associated with H2 release from AB and with AB
			oxidation.
