Summary
In this paper, I give a brief overview of the Electron Paramagnetic Resonance (EPR) spectroscopy method, and detail some of the essential background theory, such as the Zeeman effect. A detailed description of the experimental procedure to operate a Varian E-3 spectrometer is included, and a subsequent analysis of two EPR scans is shown along with a discussion of their results. The samples taken for spectral analysis were DPPH (2,2-diphenyl-1-picrylhydrazyl) and MnCl2/H2O (manganese (II) chloride in frozen water). The experiments were conducted at Dr. D. Petasis’ EPR lab located in Allegheny College, Meadville, PA, USA.
