1-Phenyl-1-propanol enantiomers (E-PP) forms the inclusion complexes of cyclic decapeptide (CDP) which were studied using the density functional theory (DFT) B3LYP method. It was also used to determine the mass transfer kinetics effect on the elution profiles of the 1-phenyl-1-propanol (PP) enantiomers on Chiracel OB (cellulose tribenzoate coated on silica gel).
