EPR is a “something for everyone” spectroscopy: 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 spectroscopy, provides detailed information about the electronic structure of metal centers with unpaired electrons and interactions with neighboring nuclear or electron spins. Samples may be in fluid solution or solid state. The research paper focuses on examining and analyzing 5 different bio-chemical samples, thereby making observations about it and its electronic structure with the help of EPR signals and their respective g-values. The g-values help us predict the structure of the compound as well as the nature of the unpaired electron .In case of hyper- fine structures, nuclear spins are also calculated for the samples. In essence, EPR is a very important technique giving us a great deal of information about the spin state of ions, the nature of ligands that surround the chemical sample, the interaction of the ions with the lattice, among others.
