Abstract

The AIMPRO density functional program was used to calculate the structures and properties of the three simplest perfluoroalkanes: tetrafluoromethane, hexafluoroethane, and octafluoropropane. The method reproduces both the molecular structures and the vibrational spectra well, and in addition, has identified a new C 2-symmetry ortho -conformer of octafluoropropane that is approximately 0.525 kcal/mol (2.20 kJ/mol) higher in energy than the well-known C2v-symmetry global minimum staggered-conformer. © 2003 Elsevier Science B.V.
