LADP-13 Electron Spin Resonance Apparatus(ESR)

Short Description:

Electron paramagnetic resonance (esr) is an important modern physics experimental technology, which has a wide range of applications in physics, chemistry, biology, medicine and other fields. This experiment requires observing the Electron paramagnetic resonance phenomenon, observing the influence of paramagnetic ions on the resonance signal, measuring the g factor of electrons in DPPH, and using Electron paramagnetic resonance to measure the vertical component of the earth's magnetic field.
