The self-diffusion coefficients (D) of alpha -humulene and myrcene, which are main components of hop oils, were measured at the temperature range of 274-372 K and pressures up to 100 MPa by the Stejskal-Tanner ET NMR method. In order to obtain motional behavior of the molecules in the supercritical conditions, the intradiffusion coefficients (D(ii)) of the two substances in carbon dioxide were also determined. It was found that the values of D(ii) are about one order of magnitude higher than that for the pure components at the same ranges of temperature and pressure. The self-diffusion data of alpha -humulene and myrcene are analysed, and the diffusion behavior of these compounds is discussed.
