Summary The retention indices of some monosubstituted benzenes, benzaldeyhdes and acetophenones have been determined on seven OV polymethylphenylsiloxane liquid phases. The interactions and forces that affect the separation of the isomers and their elution sequences are discussed, taking into account mesomeric and inductive effects of the substituents in the benzene ring and the dipole moments of these solutes. These phases are not very selective for the separation or the accurate assessment of the effect of substituent over the benzene nucleus. This may be explained by the presence of the considerable number of benzene nuclei integral to the structure of these phases.
