Abstract
Deuterium relaxation times of d- and l-α-d-tryptophan included in β-cyclodextrin derivatives were directly measured by deuterium NMR spectroscopy. The results showed that the molecular motion of the tryptophan molecule was strongly restricted even in the cavity of unmodified β-cyclodextrin and the additional recognition groupings - ammonium and carboxylate - on β-cyclodextrin did not affect the molecular motion of tryptophan, though the association constants were significantly enhanced.
