Inclusion of cresols by β cyclodextrin in DHO has been investigated by 1H NMR spectra. Although chemical shifts of the same proton are different in the cavity of empty and enclosed β cyclodextrin, only a time average peak has been detected for a proton in the spectra. The value of chemical shift corresponds to enclosed degree of cresol by β cyclodextrin. The average structure of inclusion has been determined based on 1H NMR data, it describes dynamic depth of cresol in the cavity of β cyclodextrin.
