The 46th Equation of the series is on the Zeeman Effect. In this is anomlous Zeeman Effect has been described. So what happens is, when we apply an external magnetic field, the atomic energy levels split. The change in energy is given by the formula written. Now an atomic spectral line arises when an electron makes a transition from higher energy level to the lower one. When the energy levels split, the spectral lines also split. So we'll not see a single line but multiple lines. How many? That is determined by the m value, the total magnetic quantum number, particularly written as m(j).

g is Lande's factor, particularly written as g(j) in case of Anomlous Zeeman Effect. The anomalous Zeeman Effect only takes place where the net spin of the electrons is non zero. It has many applications in Astrophysics. The Solar magnetic field was first determined by this method.
