EPR (Electron Paramagnetic Resonance) Spectroscopy, also known as Electron Spin Resonance (ESR) Spectroscopy, is a technique used to study the electronic structure of paramagnetic species. There are two main types of EPR spectroscopy: Continuous Wave (CW) EPR spectroscopy and Pulsed EPR spectroscopy. Continuous wave (CW) EPR Spectroscopy: In continuous wave EPR spectroscopy, a microw...
The sensitivity of a spectroscopic technique refers to its ability to detect and analyze signals from a sample. In the case of electron paramagnetic resonance (EPR or ESR) and nuclear magnetic resonance (NMR), EPR is generally considered to be more sensitive than NMR for several reasons: 1. Detection principle EPR detects signals from unpaired electrons, while NMR detects signals from the n...
Electron paramagnetic resonance (EPR) spectroscopy is a powerful experimental technique for studying paramagnetic species' electronic structure and properties. In EPR spectroscopy, the g-value plays a crucial role in understanding the behavior and environment of unpaired electrons in paramagnetic systems. This article aims to provide an overview of g-values and their significance in EPR spectrosco...
Scanning Electron Microscopy (SEM) is a microscopy technique that uses a focused electron beam to create detailed images of the surface of a sample. The electron beam scans the sample in a raster pattern, and the resulting signals generated by interactions between the electron beam and the sample's surface are detected and used to form an image. SEM provides high-resolution three-dimensional surfa...
