Abstract:	Goniomers of single-stranded poly(dl-alanine) $π_{dl}$ helices were treated by the semiempircal CNDO/2 MO procedure. The α_R and $α_{dl}$ forms were also calculated. From the calculated total energies and partitioned energies we discuss the conformational stablity of goniomers of poly(dl-alanines). The conformational stability of the α and π forms is also compared.

Keywords:	Polypeptides peptide stability CNDO/2 MO goniomer
