Comment on "aromatic-backbone interactions in model alpha-helical peptides" [Palermo et al., J Comput Chem 2007, 28, 1208].

Palermo et al. have recently published a method to correct for intramolecular basis set superposition errors (J Comput Chem 2007, 28, 1208) in intramolecular interactions occurring in peptides. By considering the intermolecular equivalent of this method, it is shown that the method presented by Palermo et al. underestimates the magnitude of the intramolecular BSSE.
