Abstract
Electron Paramagnetic Resonance (EPR) Spectroscopy is a powerful and
widely used analytical technique to investigate materials with unpaired
electrons, such as transition metal ions, radicals, and defects in solids,
liquids, and biological systems. EPR detects the interaction of unpaired
electron spins with an external magnetic field, providing detailed information
about the local environment, magnetic interactions, electronic structure, and spin
dynamics of the species under study. The technique is particularly valuable for
characterizing paramagnetic centers in complex materials, where it allows for
the determination of g-factors, hyperfine interactions, and zero-field
splitting (ZFS). EPR is employed in a variety of fields including materials
science, chemistry, biophysics, and solid-state physics to probe radicals, transition
metal complexes, defects in semiconductors, and biological systems. In this
review, we explore the fundamental principles of EPR, the instrumentation
involved, and its applications to study the electronic structure and magnetic
properties of paramagnetic materials. We also discuss recent advancements in
the technique, including pulse EPR and spin labeling, which offer higher
resolution and greater sensitivity for complex systems.
