Epr g-factor
WebOct 17, 2024 · The g-factor of an EPR sample determines the position in the magnetic field (at a given microwave frequency) where an EPR transition will occur. g-factor indicates field position for resonance. The g-factor is a constant but the field for resonance changes with microwave frequency. What is G factor in EPR spectroscopy? Webappears and only purely isotropic singlet EPR spectrum was observed. For both, the doublet as well as the singlet spectrum the same g-factor was observed (g = 2.00330), suggesting the same kind of the intermediate radical. The time dependence of the intensity of the EPR line meas-ured at 273 K is shown in Figure 3. Here, the intensity

For cubic local surroundings, the EPR line position is isotropic. The g factor in the simple resonance equation (Eq. 1.19) is independent of the magnetic-field direc-tion only in isotropic systems. For example, an electron in a negative-ion vacancy
Every electron has a magnetic moment and spin quantum number , with magnetic components or . In the presence of an external magnetic field with strength , the electron's magnetic moment aligns itself either antiparallel () or parallel () to the field, each alignment having a specific energy due to the Zeeman effect: where
There are three magnetic moments associated with an electron: one from its spin angular momentum, one from its orbital angular momentum, and one from its total angular momentum (the quantum-mechanical sum of those two components). Corresponding to these three moments are three different g-factors:
