A viscous vortex ring is considered as an initial disturbance to a uniformly rotating fluid. Inertial waves are generated by the disturbance and propagate through the fluid affecting the diffusion of the vortex ring with time t. The rate of diffusion is found to be proportional to $t^{\frac{3}{2}}$. This result is compared with the diffusion rates for non-rotating fluids and for conducting fluids under a uniform magnetic field.
