Abstract
The formation and geometry of the hyodeoxycholic acid (HDCA)/ 2-hydroxypropyl-beta -cyclodextrin (HP beta CD) complex in methanol-d(4) solution was determined through a rotating frame nuclear Overhauser (ROESY) experiment. The reported results confirmed those independently and previously obtained though the use of C-13 complexation shifts in the same solvent. The C-13 approach, which needs shorter experimental times and is currently used in the study of HP beta CD/bile acid systems, was then substantiated.
