Microwave-band Electron Spin Resonance Laboratory Apparatus

Electron spin resonance is named as the electron paramagnetic resonance also, which means that when the electron spin magnetic moment is affected by the electromagnetic wave of response frequency in magnetic field, the resonant transition phenomenon is to occur among the magnetic energy levels of them. This phenomenon can be observed in the paramagnetic substance (i. e. contained uncoupled electronic chemical compound) possessed of uncoupled spin magnetic moment, so the electron paramagnetic resonance is used to detect the uncoupled electron in substance and the mutual effect between electron and atom, with the result that this is an important method by which the microstructure information of related substance can be achieved. This electron paramagnetic resonance is possessed of higher sensitivity and resolution, which is able to go deep into the substance carrying out the fine analysis meanwhile the sample is not destructed and it is not interfered with the chemical reaction. At present, this technique is being applied widely in the following fields such as physics, chemistry, biology, medicine and life sciences.
This microwave-band electron spin resonance laboratory apparatus has been improved on the basis of originality. The microwave frequency counter not only is added to measure the microwave source frequency but also the digital Gauss meter is added to measure the resonant magnetic field accurately besides. Additionally, the exciting current is shown on digital gauge so that the magnetic field can be adjusted easily. This apparatus is possessed of the following features such as easy adjustment, reliable data and rich testing content, which is able to use for the modern physical experimentation and professional researching experimentation.
The following experiments can be carried out when this apparatus is used:
1. Observe the electron spin resonance phenomenon of standard sample DPPH.
2. Use the microwave frequency counter to measure the operating frequency during experimentation and estimate the required stationary magnetic field according to the resonance conditions.
3. Use the Gauss meter to measure the stationary magnetic field and calculate factor g of sample DPPH according to the resonance conditions.
4. Adjust the sample lumen in length, measure position at three resonance points and calculate the wavelength of wave-guide.
