Pulsed EPR spectrometer

Tool
BRUKER ESP 380E

Applications
Static (superhyperfinecouplings) and dynamic (electron spin relaxation times) parameters of paramagnetic systems including molecular spins (encaged atoms) for quantum information processing applications, transition metal complexes and irradiation-induced defects in solids.
