The character of spatial and spectral spin diffusion Processes in disordered spin systems is studied. The analysis is based on averaging of the rate equations, valid for fixed spin positions, over different particle configurations. New Expressions for the spatial and spectral diffusion constants are derived and compared with earlier theories.
