METHOD OF CALIBRATING ELECTRON PARAMAGNETIC RESONANCE SPECTROMETRE AND CALIBRATION SAMPLE FOR REALISING SAID METHOD

摘要

FIELD: physics. ^ SUBSTANCE: calibration sample is put into a measuring resonator, which gives an anisotropic spectrum (EPR), made from a rutile monocrystal TiO2 which contains Fe3+ ions in amount of 0.01-0.5 wt %. The calibration sample is turned in a magnetic field until appearance of an EPR anisotropic spectrum of Fe3+ ions whose lines are recorded and the EPR spectrometre is set using the said lines to maximum signal-to-noise ratio by moving the matching piston of the resonator and moving the bottom wall of the resonator in order to adjust the frequency of the resonator. ^ EFFECT: simple process of tuning and calibrating an electron paramagnetic resonance spectrometre. ^ 4 cl, 2 dwg
