## Abstract The effects on helical stability of weak polar interactions between aromatic side‐chains and the peptide backbone were examined. α‐Helical model peptides, hexa‐Ala, with sequential Tyr replacement, were investigated computationally to obtain the geometries and energetics of the interact

Abstract
In response to Van Mourik's comments on our paper (J Comput Chem 2007, 28, 1208.) we present an extended version of our rotation method. We also prove that intramolecular interaction energies as well the basis set superposition errors calculated with our rotation method are comparable with those obtained by the counterpoise method of Boys and Bernardi (Mol Phys 1970, 19, 533). In intramolecular interaction energy calculations, if the interacting groups are in proximity, our rotation method is recommended to avoid artificial interactions, which can be induced by fragmentation. © 2007 Wiley Periodicals, Inc.J Comput Chem, 2008

It has come to our attention that both in the online and published version of the above article an error occurred. On page 1210, the last equation, which expresses the CP-corrected interaction energy in solution, was displayed incorrectly. The corrected version of the equation follows. where E(solu
## Abstract 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 pres
