## Abstract The association constants for the interactions of 2‐hydroxy‐4‐methoxyacetophenone, 2‐hydroxy‐5‐methoxyacetophenone, 2‐hydroxy‐6‐methoxyacetophenone, 3‐hydroxy‐4‐methoxyacetophenone and 4‐hydroxy‐3‐methoxyacetophenone with β‐cyclodextrin in water were measured by ^1^H NMR and by isotherm
The inclusion complexes of 2-, 3-, and 4-hydroxypyridines with @cyclodextrin in aqueous solution have been studied by high field 'H NMR. All complexes showed a 1: 1 stoichiometry and the apparent association constants reflected the polarity of the guest compounds in a qualitative fashion. The inclus
