Abstract	Dedicated to Professor M. Dillinger on his 70th birthday T h e kinet ic solvent isotope effect on t h e redox react ion of U ( I V ) ions w i t h ferricyanide ions was s tudied. T h e m e a s u r e d t e m p e r a t u r e d e p e n d e n t va­ lues of &H2o/&D20 as well as t h e values of ô AH* a n d ô AS* were in terpreted from t h e p o i n t of view of t h e proposed react ion m e c h a n i s m .
