The effect of molecular motion on g- and A-tensors averaging. Field position of g-components is frequency dependent and at higher resonant frequency g-factor averages at faster motion rate. The value of hyperfine splitting does not depend on resonant frequency and averaged A-tensor value is a constant number. a Both g- and A-tensors are averaged, three line EPR spectrum; b g-tensor is averaged, A-tensor is not; c g-tensor is not averaged, A-tensor is averaged; d both g- and A-tensors are not averaged
