WebAbstract. Typical microwave frequences for paramagnetic resonance (ESR) are 1, 3, 9 or 35 GHz. This corresponds to an energy of 50 to 1500 mK.k B, respectively, 4 to 140 μeV. … WebThe ESR value is an electrical representation of losses of the mechanical crystal oscillation. A larger crystal loses less energy during oscillation, and this results in a lower ESR value. Small crystals, especially SMD crystals, tend to have higher ESR. A higher ESR value reflects the higher losses of a crystal.
