Determining the magnetic field as a function of the resonance frequency
The experiment P18.104.22.168 verifies electron spin resonance in diphenylpicryl- hydrazyl (DPPH).
DPPH is a radical, in which a free electron is present in a nitrogen atom.
In the experiment, the magnetic field B which fulfills the resonance condition the resonance frequencies n can be set in a continuous range from 13 to 130 MHz.
The aim of the evaluation is to determine the g factor.
