What you get:

Characterization of inorganic and organic materials: system electron spin, location and environment of the electron, information on the anisotropy of the molecule, how levels are occupied with temperature changes...


The electron spin resonance is the study of the absorption of electromagnetic waves by a paramagnetic compound when placed in an external magnetic field.

Materials: paramagnetic species (organic radicals, ions of transition metals and rare earths)

How to use it: no self-service unless special agreement conditions.


- X-band (9.4 GHz), Q band (34 GHz), Endor X-band and Q band
- Studies in temperature from ambient to 80K with liquid nitrogen and up to 5K with liquid helium
- Radiation in situ (soon)
