Homework Answers
A)
Normally spitting of spectral lines occur when a external magnetic field is applied, this is called zeeman effect. But in the spin-orbit coupling the magnetic moment form the electron spin affects the spectral lines. This is happening without applying any external field so it is called “Internal Zeeman effect”
B)
The spiting of spectral lines in hydrogen atoms and sodium atoms are explained by this effect. This actually proved that the electrons have a spin moment
C)
The formula for multiplicity is j = 2l+1
Where l is the orbital quantum number. For s orbital, l = 0
Hence the splitting does not occur for s states

No Brief illustration 90.3 Spin-orbit coupiny The unpaired electron in the ground state of an alkali metal atom has l=0, so j=1. Because the orbital angular momen- tum is zero in this state, the spin-orbit coupling energy is zero (as is confirmed by settingj=s and 1=0 in eqn 9C.4). When the electron is excited to an orbital with I=1, it has orbital angular...
