Rapid epr

Rapid scan (RS) electron paramagnetic resonance (EPR) has been gaining interest among researchers and developers in the field of magnetic resonance, both in academia and industry [1–19]. RS EPR promises two important deliverables: snapshot spectroscopy and enhanced sensitivity.

In rapid frequency scan EPR with triangular scans, sufficient time must be allowed to insure that the magnetization in the x, y plane decays to baseline at the end of the scan, which typically is about 5T 2 after the spins are excited. To permit relaxation of signals excited toward the extremes of the scan the total scan time required may be much longer … Log in to RapidEPR, the ultimate performance report writing tool for the military.
