The enantiomers of THD were well separated with dual CD systems consisting of S\u2010\u03b2\u2010CD and a neutral CD. The electropherograms featuring a plateau formation, which indicated the occurrence of the enantiomerization of THD were obtained. The unified equation implemented in the software program DCXplorer was employed to evaluate elution profiles and to determine rate constants of the enantiomerization of THD. Activation parameters were evaluated from temperature\u2010dependent measurements between 15 and 25\u00b0C with an increment of 2\u00b0C. The enantiomerization barriers of THD in two different electrophoretic systems were determined. Comparative studies on enantioseparation of THD using S\u2010\u03b2\u2010CDs with different degree of substitution and positions of sulfate substituent, such as randomly sulfate\u2010substituted \u03b2\u2010CD, 18\u2010sulfate\u2010substituted \u03b2\u2010CD and heptakis(2,3\u2010dihydroxy\u20106\u2010<jats:italic>O<\/jats:italic>\u2010sulfo)\u2010\u03b2\u2010CD reveal that the interactions
