Spin probe molecules bind specifically to albumin molecules … Principles and Applications of EPR Spectroscopy in the Chemical Sciences Roessler, M. M.*; Salvadori, E.* Chem. … EPR spectroscopy is inherently roughly 1,000 times more sensitive than NMR spectroscopy due to the higher frequency of electromagnetic radiation used in EPR in comparison to NMR. It gives you sufficient understanding of the properties which Bruker's EPR spectrometers read and translate into statistical data. Outline Introduction Principle of EPR The Zeeman effect The Hyperfine Effect The Hyperfine Effect Super- hyperfine splitting 2EPR 3. The basic principles behind EPR are very similar to the more ubiquitous nuclear magnetic resonance spectroscopy (NMR), except that EPR focuses on the interaction of an external magnetic field with the unpaired electron(s) in a molecule, rather than the nuclei of individual atoms. EPR Spectroscopy: Fundamentals and Methods is presented in four major parts: A: Fundamental … Principles and applications of esr spectroscopy 1.
