Abstract
Abstract The retention behaviour in reversed-phase liquid chromatography of all 25 dimethylphenanthrene (DMP) isomers on a polymeric C 18 column was investigated and could be related to their molecular shape (length-to-breadth ratios and distorsion angles of the aromatic systems). These two descriptors of the aromatic molecular shape were generated by a molecular mechanics program and will be useful in the prediction of behaviour when reference standards are not available. An application of this concept to the identification of DMP isomers in a crude oil sample is presented.
