The electron spin resonance spectrometer serves to detect and characterize the electronic properties of:
i) paramagnetic defects in solids
ii) transition metal ions in solids and solutions
iii) simple and larger molecular radicals.
The device is operated in the X-band range and has extensions that allow ESR measurements in the temperature range 10 - 500 K. Vacuum accessories and cavity resonators allow ESR measurements to be carried out in a controllable gas atmosphere and / or under photoexcitation.

Detection and characterization of radicals and other paramagnetic species
Methods & Expertise for Research Infrastructure
Using the ESR spectrometer, paramagnetic species can be investigated in different aggregate states. As a magnetic resonance method, this analytical method provides important information on the electronic structure of molecules and solids that exhibit unpaired electrons as spectroscopic special species.
Complementary equipment allows the generation of paramagnetic centers in the respective investigation system, with the help of light irradiation, heating or chemical reactions, in order to investigate their electronic environment, reactivity and stability.
