Electron Spin Resonance

The Electron Spin Resonance determines the magnetic field as a function of resonance frequency.

• All Major Components Included
• Experiment Verifies Electron Spin Resonance in DPPH
• DPPH: Diphenylpicryl-Hydrazyl
• DPPH Is a Radical with a Free Electron Present in a Nitrogen Atom
• Evaluation's Aim: to Determine g Factor

The experiment 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.
