Topic

The aim of the course is to learn the usual techniques in EPR spectroscopy on different samples, and evaluation of the results obtained.

The electron paramagnetic resonance spectroscopy is a method similar to NMR, but deals with the properties of electron spin resonance. The technique provides data on the molecular structure and dynamics of various, e.g. biological systems.

The investigation of paramagnetic materials, like free radicals, metals, and special spin-labels help to describe biological systems, e.g. membranes, proteins.
