The original aug-cc-pVXZ paper 36 emphasized electron affinities, but the paper has been cited 13,783 times, and the great majority of these papers are not devoted to electron affinities. It is well known that diffuse functions are useful for accurate calculations of bond energies and barrier heights. For example, a paper 37 on barrier heights showed that the mean unsigned errors in a set of hydrogen-atom transfer reactions involving only neutral species is 1.41 kcal/mol with CCSD(T)/cc-pVTZ and 0.70 kcal/mol with aug-cc-PVTZ. Similarly, the mean unsigned errors in a set of nonhydrogenic-atom transfer reactions involving only neutral species are 1.90 kcal/mol with CCSD(T)/cc-pVTZ and 0.95 kcal/mol with aug-cc-PVTZ. We conclude that augmentation is very useful for neutral species as well as anions.
