We note that we were not able to reproduce the C α -H BDEs of glycine and alanine dipeptides reported by Moore et al., or the BDEs of their reference compounds, although our calculations agree well with previous literature results. Their reported BDEs also differ from previous literature results at the same level of theory and using the same reference compounds by as much as 9 kJ/mol, and by over 30 kJ/mol compared to a study that uses glycine as a reference compound instead of alanine. Importantly, we and others, using composite methods or the BMK functional and the isodesmic reaction method, find the C α -H BDE of the glycine dipeptide to be lower than that of the alanine dipeptide, in contrast to Moore et al. who also report overall much lower BDEs for these two radicals.
