Description

The experiment P6.2.6.2 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 ν can be set in a continuous range from 13 to 130 MHz. The aim of the evaluation is to determine the g factor.
