EPR spectrometer Bruker Elexsys E580
A modern pulsed/continuous-wave EPR spectrometer operating in the X/Q frequency bands, equipped with temperature control (4–300 K) and ENDOR/ELDOR/DEER options. The ENDOR (electron–nuclear double resonance), ELDOR (electron–electron double resonance), and DEER (double electron–electron resonance) techniques significantly expand the capabilities for analyzing the structure and interactions of paramagnetic centers at the molecular level. The system provides high sensitivity and time resolution for studying spin dynamics, and enables determination of distances and spatial distributions of spins in complex molecular and condensed-phase systems.
A continuous-wave X-band EPR spectrometer with the capability to perform time-resolved EPR experiments. Provides high magnetic field stability and sensitivity for detecting signals of paramagnetic species. Suitable for studying the kinetics of fast processes, radical reactions, and short-lived intermediates, as well as for routine spectroscopic measurements in chemistry, physics, and materials science.
