The translational diffusion constant, D, of C60 has been determined in the even n-alkanes n-C6H14 to n-C16H34 using microcapillary techniques and Taylor-Aris dispersion theory. Experiments were conducted over extended periods of time to ensure that the solute was not associated with itself or with solvent. The D values show deviations from the Stokes−Einstein (SE) relation (D = kT/6πηr); the values of the solute's hydrodynamic radius r decrease as the solvent viscosity η increases. The data can be fitted to D/T = ASE/ηp with p = 0.903 ± 0.006 (p = 1 for the SE relation). |
