A relationship between the retention indices on nematic and isotropic phases and the shape of polycyclic aromatic hydrocarbons

  • A. Radecki
  • H. Lamparczyk
  • R. Kaliszan


An equation has been derived allowing to predict retention index values on nematic phases from computable parameters and sizes of the molecules of polycyclic aromatic hydrocarbons. Another equation, which has also been derived, allows to determine the shape parameter of a molecule from chromatographic data.
