EPR100 Pulse Electron Paramagnetic Resonance Spectrometer
Introduction: Electron Paramagnetic Resonance (EPR) spectroscopy technology is a spectroscopy method for studying the structure, dynamics and spatial distribution of substances containing unpaired electrons. It can provide in-situ and lossless electron spins, orbits, and atomic nuclei. Micro-scale information. When a substance containing unpaired electrons is placed in a static magnetic field, if an electromagnetic wave signal of a certain frequency is applied to the sample, the emission or absorption of electromagnetic wave energy by the substance will be observed. By analyzing the changing laws of electromagnetic wave signals, the characteristics of electrons and their surrounding environment can be simplified, so that the analysis of material structure and other applications can be carried out. Electron paramagnetic resonance can be used to accurately, quickly and non-destructively obtain material composition and structure information. Substances containing unpaired electrons are widely distributed, such as isolated single atoms, conductors, magnetic molecules, transition metal ions, rare earth ions, ion clusters, doping materials, defective materials, biological free radicals, metal proteins, etc.; many substances do not contain themselves Unpaired electrons will also produce unpaired electrons after being excited by light. Therefore, electronic paramagnetic resonance (EPR) technology is widely used in important fields such as physics, chemistry, biology, geology, archaeology, materials science, medical science and industry.
