A data acquisition procedure, outlined in Fig. 2, has been developed that takes the difference between two scans that are designated as scan 1 and scan 2. In the difference scan the background cancels and the EPR spectrum is doubled, thereby increasing the signal-to-noise by a factor of square root of 2.
