description

Abstract The geometries of two octacyclopeptides, cyclo[( d -AmP- l -AmP) 4 ] (AmP=α-aminopentanoic acid) and cyclo[( d -Ala- l -Phe) 4 ] were obtained by DFT and ONIOM methods. The resulting data show a substantial agreement with a computing time about three times lower in the case of the ONIOM procedure. This can be exploited in the study of polymeric structures set up by cyclopeptidic monomeric units.
