Abstract
A new method for precise absolute determination of radical concentrations by EPR is described. Cavity quality factors, cavity mismatching, power levels and receiver characteristics do not have to be measured. The measurement of radical concentration is reduced to the determination of geometrical factors, the area under the EPR absorption curve, the LF modulating field strength and a frequency change. Accuracies in the 0.5% range can be reached. The method is checked by and bared on complex function theory.Mesh：
