| Abstract: Inclusion of cresols by β-cyclodextrin in DHO has been investigated by 1H NMRspectra. 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. |
