Abstract
Electronic structure is an important concept in chemistry. Among the techniques that can be used to understand electronic structure, EPR spectroscopy is unique in the sense that it can specifically probe paramagnetic molecules. This paper describes a number of fundamental concepts of EPR spectroscopy and its application to paramagnetic transition metal ions. As examples, EPR spectra of two paramagnetic metalloporphyrin complexes are used to define electronic structure of these molecules. The concepts described can be used in upper-level undergraduate and first-year graduate classes.
