SEUNG‐JAE … The ESR spectroscopy has been used to estimate polynuclear hydrocarbons, which are first, converted in to radical cations and then absorbed in the surface of an activated silica-alumina catalyst. An intense external magnetic field produces a difference between the energy levels of the electron spins m s = + ½ and m s = - ½, leading to resonance absorption of an applied microwave beam in the spectrometer. Electron Spin resonance spectroscopy is based on the absorption of microwave radiation by an unpaired electron when it is exposed to a strong magnetic field.
