Introduction to EPR Spectroscopy: Theory, Instrumentation and Applications

The KAUST Imaging and Characterization (IAC) Core Lab, proudly invites you to a comprehensive introduction to EPR spectroscopy, covering its theoretical foundations, instrumentation and wide-ranging applications. This method is the only method for directly identifying paramagnetic species with unpaired electrons and offers a powerful tool for studying various samples, including organic free radicals and paramagnetic materials. When NMR spectroscopy falls short in identifying paramagnetic materials, EPR serves as a valuable complementary technique. EPR spectroscopy enables investigation into topics such as materials defects, transition metal ions, spin-labeled materials, electron transport kinetics, optically stimulated materials, geometric and electrical structure, coordination of complexes, and membrane structure elucidation. It finds extensive use in photocatalytic chemistry, including reactions, catalysts, energy storage, electron transport, and exploring metal complex oxidation. Experts from multiple centers at KAUST have successfully applied various EPR methodologies in catalysis, solar energy, membrane research, structural biology, battery technology and energy storage.


The course covers the following key topics:

1. Basic concepts: Spectroscopy, electron spin, orbital momentum, total angular momentum, Bohr magneton, g-factor, gyromagnetic ratio, Larmor frequency, Schrödinger equation, Eigenfunctions and Eigenvalues, Spin Hamiltonian, and Interactions.

2. Instrumentation: EPR Magnet, klystron, microwave guidelines, EPR cavity, resonators, and EPR spectrometer.

3. Applications: Photocatalysis, solar cells, batteries, energy storage, organic radicals, and structural biology.


Who Should Attend:

This course is designed for KAUST researchers as well as selected academics and professionals from Saudi universities and businesses who intend to utilize EPR spectroscopy as a primary research technique. 


Course Schedule:

The course will be conducted over 5 days and will include lectures, practical demonstrations, and hands-on sessions. The schedule will be provided upon registration.



Participants who successfully complete the course and pass the examinations will receive a certificate of completion.



The NMR laboratory at KAUST is equipped with X-band and pulsed CW-EPR spectrometers, which are extensively used in both solid-state and solution-based applications involving paramagnetic species.
