Electron spin energy level, schematic representation

Figure 23.1 Schematic representation of the splitting of electron spin energy level due to the Zeeman effect. The gray background blur represents the uncertainty of energy levels due to the Heisenberg uncertainty principle Ae At > ft/2.

Figure Bl.15.8. (A) Left side energy levels for an electron spin coupled to one nuclear spin in a magnetic field, S= I =, gj >0, a<0, and a l 2h)<(a. Right side schematic representation of the four energy levels with )= Mg= , Mj= ). +-)=1, ++)=2, -)=3 and -+)=4. The possible relaxation paths are characterized by the respective relaxation rates W. The energy levels are separated horizontally to distinguish between the two electron spin transitions. Bottom ENDOR spectra shown when a /(21j)< ca (B) and when co < a /(2fj) (C).
