Rapid epr

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 …

Since post-processing phase corrections require accurate lineshapes for both the absorption and dispersion signals, the background removal method must work for both.

In rapid scan EPR the rapidly-changing magnetic field induces a background signal that may be larger than the EPR signal. A method has been developed to correct for that background signal by acquiring two sets of data, denoted as scan 1 and scan 2. In scan 2 the external field B 0 is reversed and the data acquisition trigger is offset by one ...
