ChemistryOfTransitionElements: Russell-Saunder's coupling

For PG, MPSC, and UPSC students.
After studying this point you will be able to understand:
1. What interaction takes place between magnetic fields produced by each electron present in the subshell?
2. How does the total orbital angular quantum number (L) couples with total spin angular quantum number (S)?
3. How are the Full Spectroscopic Term Symbols derived from L and S coupling?
4. How to explain L-S coupling in p-subshell with 2 electrons?
5. How to show Full Spectroscopic Term Symbols for metal ions with p- subshell containing 3 to 6 electrons?‪@dr.armschemistry4541‬
