    b-CD) cavity protons as well as roxatidine acetate hydrochloride aromatic ring protons revealed the formation of a RAH–b-CD inclusion complex. Detailed FTIR and NMR spectroscopic (1H NMR‚ COSY‚ NOESY‚ ROESY) studies have been done. The stoichiometry of the complex was determined to be 1:1‚ and the overall binding constant was also determined by Scott’s method. The NOESY spectrum confirmed the selective penetration of the aromatic ring of RAH into the b-CD cavity in comparison to that of the piperidine
