Abstract: Error sources in quantitative EPR spectroscopy of solid state materials with sample shape and sample packing procedure have been analyzed, It was found that The differences in the shape of bulky, solid state materials (despite being of identical material, volume, and sample mass) can cause EPR signal intensity differences of 200-500 %. The differences in the sample tube packing procedure of the powdered/polycrystalline materials (despite being of identical material volume. and sample shape) can cause the EPR signal intensity differences of 17-21 %.
