Received March 6, 2008 Abstract — ESR spectra are calculated for aggregates of mono- and polydisperse particles designed by special algorithm and characterized by preset values of fractal dimensionality and prefactor. The dependence of ESR spectrum on the aggregate size, fractal dimensionality, external field (for anisotropic aggregates), and character of large and small particles packing in the aggregate in the case of polydisperse system is demonstrated.
