Abstract The 1 H and 13 C NMR spectra of heptakis(2,6‐di‐ O ‐pentyl)‐β‐cyclodextrin in deuteriochloroform have been fully and unambiguously 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.
