Separation of active multiple electron spin signals in electron paramagnetic resonance

摘要

A system and method involve performing electron paramagnetic resonance on an object under study. The system comprises a first field generator adapted for generating an orienting magnetic field for orienting the magnetization of the object under study and a second field generator adapted for generating RF excitation waves at a frequency to generate electron paramagnetic resonance (EPR) in the object under test. The system also comprises a detection unit adapted for detecting the EPR signals emitted by the object under test and a control unit adapted for controlling the relative orientation of the orienting magnetic field induced by the first field generator with respect to the detection unit. The system furthermore comprises a processing unit programmed for combining detected EPR signals obtained using different relative orientations of the orienting magnetic field with respect to the detection unit.
