Experiment: Electron Spin Resonance, 230V
3B Scientific, UE5030100-230, Experiment for Atomic Physics: Electron Spin Resonance, 230 V, 50/60 HzUE5030100-230 Includes Only:PC Oscilloscope, 2x25 MHzESR-NMR Control Unit (230 V, 50/60 Hz)HF Patch Cord, 1mESR ModuleFeatures:Objective: Demonstrate electron spin resonance in DPPHElectron spin resonance (ESR) is based on the energy absorption by substances with unpaired electrons, which are inside an external magnetic field produced by a DC source. The energy is absorbed from a high-frequency AC-generated field which is fed in perpendicular to the field from the DC source. If the frequency of the alternating field is equal to the resonant frequency, the impedance of the transmitting coil filled with the test material changes in accordance with a resonance curve and a peak will be visible on an oscilloscope screen. One suitable material for this is diphenyl-picry-hydrazyl (DPPH).For more information, please see Data Sheet.
