Mutual and tracer diffusion coefficients at 25$sup 0$C are reported for the liquid systems perdeuterobenzene(C$sub 6$$D$$sub 6$)-chlorobenzene, benzene(C$sub 6$$H$$sub 6$)-chlorobenzene, C$sub 6$$D$$sub 6$-n-octane, C$sub 6$$H$$sub 6$-n-octane, C$sub 6$$D$$sub 6$-cyclohexane, and C$sub 6$$H$$sub 6$-cyclohexane. These data are compared with similar data previously obtained in this laboratory. All the data indicate a very slight isotope effect for tracer diffusion of benzene in benzene, in chlorobenzene, in n-octane, and in cyclohexane. Application to the above data of the equation usually used to describe the ''isotope effect'' in solids, indicates that diffusion in these systems may be governed to a large extent by the viscosity of the solvent.
