Abstract
The inclusion process of a "'bifunctional'' guest molecule, butyl L-tartrat e (DBT), into the alpha-cyclodextrin (CD) cavity has been studied with two different experimental techniques, H-1 NMR and UV. The experimental data ha ve been analyzed supposing two different reaction models: the first model s upposes that only one of the two butylic residues can be included in the CD cavity, while the second one considers that also the other butylic tail ca n be included in a second CD cavity. This second model seems the more appro priate for describing the DBT-CD inclusion process. The results are discuss ed briefly.
