Abstract Calorimetric studies of the inclusion complexes of straight and branched alcohols and of diols with alpha-cyclodextrin (α-CD) have been carried out in water solvent. The data suggest that straight and branched chain alcohols enter the cavity of α-CD alkyl end first. The hydroxyl group hydrogen bonds to the outer oxygen ring of the cyclodextrin. For branched chain alcohols the longer alkyl part of the molecule penetrates the α-CD cavity up to the hydroxyl group. Diols form two hydrogen bonds to the outer oxygen ring of the cyclodextrin with some penetration into its interior.
