Summary
EPR spectroscopy is a very powerful bio-physical technique: practical and useful EPR applications on biomolecules and models can range from very simple to very involved experiments and analyses. Electron paramagnetic resonance spectroscopy, also known as electron spin resonance, provides detailed information about the electronic structure of metal centres with unpaired electrons and interactions with neighbouring nuclear or electron spins. It has been used by scientists over the years to look for free radicals within compounds. These free radicals take part in various organic and inorganic reactions and detecting them are crucial in a wide variety of research applications. Therefore, this paper serves as
an experimental and theoretical introduction to the file of EPR spectroscopy.
Over the course of this paper, various chemical samples were tested on a Varian X-Band spectrometer, with the purpose of predicting the g-values of these compounds which help us detect not only the free radicals present, but also, to decode the chemical structure of the given sample.
