Electron Spin Resonance (ESR/EPR) is an important tool for fundamental studies in many fields.
Radicals are studied with ESR in life sciences, environmental chemistry, research in food safety/quality, the petrochemistry, bioinorganic chemistry and many more, together with studies on metal compounds, antioxides, etc. ESR is the standard for many dosimetric application in e.g. electron beam and neutron dosimetry of alanine tablets to determine irradiation doses. Solid state physics applications include the investigation of paramagnetic centers and their orientation within a crystal.
