China Wholesale Fluorescence Spectrometer Factory – LADP-3 Microwave Electron Spin Resonance Apparatus – Labor Detail:

Electron spin resonance is also called electron paramagnetic resonance, which refers to the phenomenon of resonance transition between the magnetic energy levels of the electron spin magnetic moment when it is affected by the corresponding frequency electromagnetic wave in the magnetic field. This phenomenon can be observed in paramagnetic materials with unpaired spin magnetic moments (i.e. compounds containing uncoupled electrons). Therefore, electron spin resonance is an important method to detect uncoupled electrons in matter and their interaction with surrounding atoms, so as to obtain the information about the microstructure of the material. This method has high sensitivity and resolution, and can be used to analyze the material in detail without damaging the sample structure and no interference to chemical reaction. At present, it is widely used in the research of physics, chemistry, biology and medicine.

 

Experiments

1. Study and acknowledge electron spin resonance phenomenon.

2. Measure Lande’s g-factor of DPPH sample.

3. Learn how to use microwave devices in EPR system.

4. Understand standing wave by changing resonant cavity length and determine waveguide wavelength.

5. Measure standing wave field distribution in resonant cavity and determine waveguide wavelength.
