Effective lande g factor
WebJul 1, 2004 · The g-factor of a level, denoted as αJ, belonging to a pure LS-coupling term is given by the formula (2) g αLSJ =1+(g S −1) J(J+1)−L(L+1)+S(S+1) 2J(J+1). This … Webis called the Landé g factor for the particular state being considered. Note that if s =0, then j = l so g =1, and if l =0, j = s so g =2. The Landé g factor thus gives some effective gyromagnetic ratio for the electron when the total dipole moment is partially from orbital angular momentum and partially from spin.
