The 1H and 13C NMR spectra of heptakis(2,6-di-O-pentyl)-β-cyclodextrin in deuteriochloroform have been fully and unambiguousy assigned.Several methods, including homo- and heteronuclear spin decoupling, two-dimensional homo- and hetero-nuclear correlation NMR spectroscopy, spectral simulation and the measurement of relaxation times were used for chemical shift assignments.
