Electron Magnetic Resonance Principles

Description

If a magnetic moment (vector) of the electron is placed into an external magnetic field, it would be divided into two different levels: one parallel to the applied field (high level), and another antiparallel to the field (low level). The magnetic moments of low level transit to the high level when they absorb an appropriate frequency of electromagnetic wave under certain conditions. Such transition is called magnetic resonance transition. When the course of the magnetic moment is from the electron, it is called “electronic magnetic resonance” (EMR) transition; when the course is from the nucleus, it is called “nuclear magnetic resonance” (NMR) transition.
