The JES-FA series can be applied to all electro spin resonance measurement ranging from routine to specialized research study. Uses three types of high performance magnets to study chemical species that have one or more unpaired electrons, such as organic and inorganic free radicals or inorganic complexes possessing a transition metal ion. Electron spin resonance can also be used to measure magnetic fields, however compared to the NMR method the accuracy is rather low due to the signal width. Apparatus: The equipment used in this experiment is very similar to that used in the NMR experiment, the difference being that the magnetic field is produced by a pair of large Helmholtz. The electron configuration of the ground state of the isolated Cr+3 ion is 1s22s22p63s23p63d3 (4F 3/2) with only three 3-d electrons outside of closed shells. From Hund's rule the ground state has an orbital angular momentum L=2+1+0=3, or an F state and a spin angular momentum of S=3/2. These couple through the spin-orbit.

Ordinary radar equipment and microwave ovens. 1.2 The Zeeman Effect An isolated electron, all alone in space without any outside forces, still has an intrinsic angular momentum called "spin", ̅. Because an electron is charged, the angular motion of this charged particle generates a magnetic field. With a resonance curve and a peak will be visible on an oscilloscope screen. The cause of resonance absorption is the "tipping over" of the magnetic moments between spin states of a free electron. The resonant frequency de-pends on the strength of the DC-generated field and the width of the resonance signal is related to the uniformity of the.
